I was born in 1964. I remember watching Popeye the Sailor when I was a little kid... I never imagined I'd hear him warning me about refilling propane cylinders when I was 60.
I'm cool with the warning part of his message but I don't want to eat any spinach. Definitely throw the spinach cans away, full or empty and never reuse them!
I’ve refilled these things like crazy and I have had no issues so far but that’s not to say that it couldn’t happen. I used to haul bulk propane via 18 wheeler-10,000 gallons/ 44,000 pounds at a time. I have been burned by liquid propane on my legs (frostbite) and that is horribly painful, sometimes months . Propane is really nothing to mess with- If a tank ruptured then you are likely to either have nasty frostbite or you could be burned if it somehow combusts. Liquid propane looks and acts like water- it will soak right through your clothing and wet your skin for a split second and then evaporate and leave you with nasty frostbite before you have time to do anything about it.
Back in the 70s a friends dad who is a farmer used to use propane to run all his tractors, he would crack the propane valve and let the cold gases chill his beer. One day the propane bounced back instantly freezing his left eyeball leaving him permanently blind in that eye
That's why they're using it as refigerant now - R290 - aka propane! Basically anything is a refrigerant if it has a boiling and evaporation point at the right temperature and pressures
@@gorak9000 And you can also adjust the pressure and temperature to adjust the evaporation point. You can use that to make passive no moving parts heatpipe coolers ;)
Refrigeration people have always known this. But the old refrigerators had exposed coils. Pock a hole in one with a knife trying to get an ice cube tray out and Boom.@@gorak9000
I don’t know what it is about human nature, but I don’t like somebody telling me I “can’t” do something and tend to block them out…but when somebody explains to me why I “shouldn’t” do something, I perk up and am very interested in what they have to say. Thank you for this video.
It's the "I need to see it for myself" thing, and with so many people armed with false information, it's good to be skeptical. I wouldn't have believed it if I didn't see it.
Like people telling me i can't eat random mushrooms. Sure i can, but i would likely die from eating a poisonous one or become really sick. Even professional pickers can make an error if they go to new locations. So yes you can do nearly everything but should not do even half the stuff.
Seal the top of the cylinder with duct tape to stop the valves from leaking if they go bad. ......there's your Red Green contribution. @@ReliablyRandom-BuildsReb-rg7mv
I myself have decided that I'll refill perhaps twice and then discard. Like you...I have refilled many times. I used to have one of those single use containers that I refilled countless times. I discarded it when it became leaky and switched to another. This was quite some time ago and I still have that second container. I'm not convinced to stop altogether, but now I'll replace sooner this time. Thanks for the comment.
Disposables are not cheap to purchase, so refillables would be a reasonable value. I did not know refillables were available. Thanks.@ReliablyRandom-BuildsReb-rg7mv
@@ReliablyRandom-BuildsReb-rg7mvthats a very good deal. I mean considering the disposable cylinders are like 5-7$ each, and the gas is like 2-3 dollars per pound if I recall correctly (in a 15lb tank) these cylinders will pay for themselves in just a few uses. And the cost is not that much more than starting with a disposable bottle and re using it. This is good information to have. That’s a big improvement in safety for a only a slight cost increase.
That's what I was thinking too. When he said that they argued with him that they had refilled one 40 times with no issues, I thought 'you will only have an issue with it one time'
I had no idea that there were refillable cylinders. I was already concerned about refilling single use cylinders, but now I will buy some of them. I was a carpenter, so worrying about compressor tank rust was always a concern for me. Thanks for that explosion that *won't* happen to me!
I have one point to add, Disposable cylinders used to be a lot thicker but now they are thinner, How do i know? I used to tare mine then all the sudden they lost about 20 percent weight. So I bought the hose setup to run my stuff. But i did not know about refillable so thank you for that boon.
How long ago did that happen? Because I still have a few old ones I've been meaning to refill. If they're thick enough, I'd probably still take the risk. Maybe give 'em a shot of WD-40 inside first.
Great video! I'm glad you survived cutting them open. Your visual of squeezing and bending the refillable was very compelling. I've not seen anyone do that and I've seen a lot of videos about refilling them. I tried it, but the green ones are very finicky to re-fill. And those valves are not meant to be poked at like a bicycle valve. I have some Flame King cylinders on the way now.
@@ReliablyRandom-BuildsReb-rg7mv I would like to see a follow up on the torch bottles like mapgas or propane. The taller slender bottles, approximately the same fluid oz.
@@ReliablyRandom-BuildsReb-rg7mv One of a kind, she is. One of a kind with a personality to match, is her gift to the world. I hesitate not to recommend her companionship to anybody.
I think I actually bought the fitting about a year ago. I'm throwing out my one-use bottles, and looking at refillable. Thanks for a very well illustrated point presented logically.
Certainly, if one is going to be refiling the cannister 20-30 times or more per year, spring for a refillable. But for emergency or occasional use, I just can't get too excited about it. ETA: Still, a well thought out and presented argument and you get a thumbs-up from me.
Im just pointing out that the general population does not always understand that difference and was trying to show them. Just remember single use cylinders aren't stress tested for a reason. They are one use. metal fatigue is not taken in to account the same. One bad shoe comes through and makes a tank and someone looses a hand over not spending 14 dollars
@@ReliablyRandom-BuildsReb-rg7mv Always check your information in regards to the laws on pressure gas cylinders! Do your homework. You've just stated that these pressurized propane cylinders aren't stress tested, think again! If these pressurized cylinders weren't stress tested, they would not meet the law requirements and couldn't be sold to the public or anyone else! These cylinders are all safety tested and have built in safety relief valves. Note: ALL propane tanks, including the cylinders you use for your grill, are required by law to have pressure relief devices that allow for the release of excess pressure inside the tank.
The danger is when you are using it and it ruptures and sets you on fire and everything around it. Worse they get stored inside and rupture in the basement next to your gas appliance... etc. @@chuckfry1227
I have been refilling the single use cylinders for many years BUT I mark a date on the outside and after the 3th refill, I toss them. I didn't know there were 1lb cylinders that were made to be refilled. I thank you. I'll certainly check into those. Good video. Thanks
I certainly do a lot of refilling of the single use cylinders with no problems. In my experience the ports start leaking before any catastrophic failure. Bringing me to my next point as I agree siding with precaution is good with designed refillable containers, some references for context of actual catastrophic failure should be presented in a video like this to really drive your point home considering rupturing of these cylinders is NOT a common enough occurrence to concern most people. I for one will be upgrading from now on to refillables due to this video and my growing concern of my aging cylinders. Thanks for the video.
@@ReliablyRandom-BuildsReb-rg7mv no question, I immediately use them in my portable heaters and dispose after empty. Thanks again for the video. Definitely shed some light on disposable bottles, another side note I’ve had prolly half of my bottle “balloon” out concerning amounts but again never failing. It would be interesting to see a video of testing to failure with filled Coleman bottles being exposed to common extreme temperatures with drop and crush scenarios, in controlled environments of course.
I have been refilling my tanks for a while. I NEVER fill them all the way, just half way, better to have a lot of tanks than a possible over fill accident. thanks good show.
Are you the same guy that goes to the centre of a frozen lake and makes a hole to see just how thick the Ice is ? just a FYI no pressure in a tank propane boils off That is why at - 40 propane is useless as a fuel.
Propane boils really fast at room temp but if that liquid propane hits you it will boil off of your skin and leave you with severe frostbite. I have the scars to prove that and I will have them for the rest of my life.
Great video . . . reminds me of something my Dad says . . . "Just because you 'can' do something, doesn't mean you 'should'. Appreciate you taking the time to do this video Sir.
something I was definitely not expecting to find was rust. that is more than enough for me to say "no thanks, I'll pay the extra for a refillable bottle"
Always wondered why the label said something to the effect of it being illegal to transport if refilled on the disposable cylinders. Also never knew there were refillable 1 pound cylinders. All I know for certain is that they are always empty when I need one.
I only bought some FlameKing bottles because I need to have something DOT approved in my semi; they're tremendous! I was refilling disposable Coleman bottles for four years, and running my Buddy heater on them all winter... never had a clue! O^O
I was starting to save the used single use bottles to refill later. I've never refilled one before but had seen plenty of videos on how to do it. After seeing your video, I will not chance it. I saw a video of a air compressor that exploded because it was rusted on the inside. Took out half a guy's garage. I realize these are smaller and less pressure but it would be enough to ruin your day. Not worth the risk. Thanks.
Well crap! I save my empties and occasionally refill them. You make a strong argument against the practice. I have proved the refillable tanks in the past and sort of choked on the price. Now I know why they cost what they do. Thanks for taking the time to make the video and also for sacrificing two of your tanks.
It only takes one time to "Have a problem" with a single use container and you won't be here to complain about the cost of a refillable. Notice the difference in the quality of the valve too. Thanks for the demo to drive it home !
Had a half used Coleman tank that I had used several times then one day the valve wouldn't close even after a couple of tries, put it off to a safe place and it became an ice cylinder. Luckily I had brought a spare tank along on that trip.
I had seen the adapter kits a while back to refill those small canisters that go on the buddy heaters. Good to know they actually sell reusable small canister. One-time use canisters is just asking for problems.
Good presentation, and Facts. I had a blue propane cylinder and a old torch tip for soldering plumbing fittings i used to start fires in the old burn barrell outside. I fired up the torch and could not shut it off, if had to burn if self out, lucky it was outside. Not sure if the cylinder or torch tip was defective, threw both in the garbage when they cooled off.
I guess the Lord Jesus led me to this video, i bought the refill tool years ago , watched others supposedly refilling them, i myself couldn't make it happen, thought id try again sometime....then you showed up ....PRAISE THE LORD, thank you for caring, you may be saving lives. Now if all who call on the Lord , Repent and believe the Gospel , their soul shall be saved. God bless you sir. I pray Jesus knows you.
By far the best part of this video is his voice. That voice rocks! It is the voice of someone who has f-ed around and found out a few times, learning good life lessons.
I have refilled the single use canisters more than once without any issues. I personally feel like people are going to do whatever they are comfortable with doing either way. The cost of the single use propane cylinder is too expensive if you’re using a large amount of them. I really like your antique fans, careful not to stick your hands too close to the blades when it’s operating 😮.
Never had a problem with my vintage fans and fingers. I would always stick my fingers in the fan from the front and never had a problem because of the way the fan blade is made. Now if you stick your fingers in front the back you will remember that forever.
Good video. I have a few single use ones that are about 15 years old and I have refilled them countless times. Probably time to switch them out. I never thought about them rusting from the inside. Thx for cutting them open and showing 😀
I am 60. Have never once heard of one cannister after refilling, even after multiple refills caused any danger. Not once. Not saying it cant happen. If it does it will be a valve issue. And that can happen just as easily with the refillable cannisters. Just saying! Like that pro- mo and link you gave the expensive refillables! Just sayin!!!
The mass & thickness of the steel & the rust inhibitor are all very noteworthy distinctions This is all solid information. There's no excuse for rust in the NO LONGER CHEAP Coleman cylinders. Even single use should simply use dehydrated air at the very least. In my experience these bottles can fail 1 of 2 ways. 1. Most common: Slowly, oxidation finally weakens the steel enough to cause a small leak. 2. Less common. Fast, eExplosion due to heat &/or weakened steel.
U Are A Good Sport ----- And I Did Not Know They Made Refillable 1Lb Propane Cylinders ----- I Will Find Out Where I Can Get Some ------- I Have Filled My Last Single Use Tank ----- Thank You 4 The Heads Up
I have been using these refilled Coleman cylinders for 20+ years without a single issue. Each time they get refilled, I mark them.. When they've been refilled 15 times, I throw them out. I also adjust the refill count if they have been stressed, like accidentally leaving one in a hot car, or hooking it to something that uses all the propane up really quickly and causes the cylinder to frost. I've never had a problem and I've never heard of anyone having a problem.
Right at the Start! I Love that old fan you have behind you! I have a couple old beauties, from the 30s - 40s. All original and they still work. 👍👍👍👍 😁✌🖖 P.S.: Oh, there's more. I didn't notice, the first time. Cool!
I couldn't agree with you any more than I already do...yet I refill small cans about every 3-4 days. I fill them from a tank I acquired in a storage unit I purchased...more on that momentarily. As for the Coleman type tank you cut up, I hate to refill those more than once or twice. Why? Because they grow at an unacceptable rate. Any growth is scary. Since I fill as a liquid from a massive cylinder occasionally in 120-degree Arizona weather...the big cylinder pressure can be quite high. The small diameter taller type mini cylinders are far more robust and never grow at all. I wish you would have cut one of those up as well. These tall mini cylinders qualify as much less dangerous in my 'never cut one up semi-professional opinion'. While I have everyone's attention, I would like to get some opinions on my big tank. The tank is cool because it is almost 100 years old! It measures 14X50 floor to top of threaded valve protector cap. It has the following information on it: ICC-4B240, 16549, BBGC W.C.239#, PST T.W. _ _ . The following re-certification dates 12-45 (Note: the PST seen above directly follows this first date, has identical font and depth and is in line with the blank T.W. line), 10-58 E, 3-69 E, a very weak stamp that looks like the top of a 0 or 8 followed by 7A=, 8-85.S, 3-96 E. Property of BEMIDJI Bottle Gas Co. To the best my knowledge this tank had its first re-cert 12 years after it was made making it pre WWII and around 1933. Is that correct? What does ICC-4B240 16549 mean? Is it time to let it die or should I get it re-certified? I would like to paint the outside if this is legal because it has light surface rust where the silver paint has worn off. Any information on this would be appreciated.
I bought several years ago an adapter to refill the one time use tanks from a regular propane tank. Never did use it, I'm kind of glad I haven't and I'm not going to use it now.
All refillable gas bottles have to be hydrostatically tested at set intervals. Stamped and dated. The thin one time use ones are a ticking time bomb if you are refilling. Each time you pressurise and depressurise the bottle gets weaker. Rust is a factor. That can depend on the how pure the gas that goes in is and filling method. An open hose will get humidity inside it if not purged first then it goes in bottle and will cause rusting.
Devil's advocate here. Wouldn't the same phenomenon apply to a car's brake system every time you pump the pedal? I mean, here on Earth, we're immersed in an oxygen-rich environment, where every single object is being subjected to a continuous barrage of erosive physical and chemical degradations; strictly speaking, everything is a ticking clock-ourselves included. It's hard not to wonder whether the _risk_ portion of risk/benefit might be getting somewhat overstated here. I'm also thinking a quick pulse of WD-40 before refill could oar back the rust sharks for a bit. IknowIknow, it's only a _de facto_ inhibitor. But that's kinda my point: everything is.
The car braking system is devided front and rear so a total fail is very very rare. Mixing any thing in with the propane could cause a problem with materials in regulators and seals on devices it use in if they are not compatible. @@pocket83squared
@@pocket83squared100%. A them cans even at 100° are still under 200psi. An very unlikely to just bust. Even if it rusted it’s going to be a pin hole.

@@pocket83squaredThe brake system on a vehicle is a CLOSED system, after the master cylinder, and the only air that gets in there is when it's opened to refill it. Have you never noticed the rubber seal poking down on a very low system?
@@pocket83squaredbrake systems are designed to fail soft. That is there is indication before complete failure. In brakes it's the dual circuit that does this. Combined with regular (yearly?) inspection and testing, the corrosion you describe will be spotted or not be disastrous.
Thank you for the video. I did NOT know they made refillable cylinders. THAT is a splendid idea and there is no way I would risk refilling a disposable when the price premium is so small and the safety margin is sooooo large. Yes, I ***AM*** a cheap old man but not so cheap as to be "stupid cheap". Just a nitpick: It would be really helpful if you at least listed the types/name of the refillable cylinders in the dooblydoo. I did of course figger it out but I am lazy as well as cheap. :) Peaceful Skies.
Ok.. i refill my propane bottles and have for about a year…i check for any leaks or rust around the orifices.. i also check the weight when i fill them.. if i see any “ anomolies” i toss them.. but i have refilled a few of the good ones probably 10 times with no problems.. BUT thanks for your opinion.. i will keep safety in mind always.. 🔥🔥🔥🙈🙉🙊❤
I've considered refilling the small single use cylinders before but something just didn't seem right with it. Now I no why. I was a volunteer firefighter back in the 80's. A couple of bucks savings just isn't worth the risk your taking when refilling a thin cylinder with one of the most highly explosive gases known.
I am a DIY guy and often work alone doing dangerous things safely * (Diesel creek reference check him out) in my 20s my brother, a chemical engineer warned me about welding and messing with pressure vessels, I did not appreciate until my 50s just how dangerous they can be.......there are plenty of videos here on RU-vid how dangerous pressure vessels can be. Please check them out if if you are thinking about making or modifying a pressure vessel.....I still force air into an empty aerosol can that has no pressure but still has paint or lub in it but I limit it to around 90 psi and I probably should not do that either....
*Propane Cylinder, has taken my sight* *Taken my speech,* *Taken my hearing,* *Taken my arms,* *Taken my legs,* *Taken my skin,* *Left me with life in hell*
Thank you for doing this and taking the financial hit of cutting up refillable cylinders to make the comparisons. It at least gives folks an informed choice. As other people have posted here I too think that the single use Worthington type cylinders have now been cheapened enough that refilling them isn't worth the risk any more.
Thanks to your video, I am disposing of all my old cylinders. I did have plans to refill them, even bought the coupler to do it but not gonna do it now. Not safe at all. I had no idea... Thanks for the heads-up!
I could not find any reference saying they cant be refilled. The extra weight is with the built in heavy duty manifold adapter you didnt show. If these were that dangerous they would be required to be manually restricted to one time fill only. I have crushed and shot empty propane cylinders of all kinds and there pretty well made. Most of all Why would you buy a $30-40 refillable cylinder versus a $8 disposable. Then your only using a rubber hose to connect it to appliance. If they were dangerous they would be banned.
You made a good point there. I never thought about rust developing in the container. That could flake off and clog the pores in a heater or stove and then you would be sunk. Now i'll need to see if the one pounders will fit in my Buddy with a filter.
Didn't even know they made 1# refillable. Well worth the extra money not to have the explosion potential especially when you're standing in front of it while refilling. Consider this vid to be PSA
Great video, and thanks for the info. I was not aware of the difference. I don't use those small propane tanks but still good to know. PS. I like those 5 old fans around you. .
Propane has no oxygen molecule which maskes oxidation of the steel impossible. H20 on the other hand does.when you fill your 1lb always turn the 20 over and let it sit for 20 minutes before opening the valve. If you look at a opd valve your not pulling off the very top of the cylinder so allows room for the water to settle.
When those refill adapters first hit the market over half a century ago those fat short tanks didn't exist. I think all the tall skinny tanks were quite thicker metal back then. Propane is a low pressure gas so the risk of rupture from pressure is low. The valves eventually start leaking and I throw them out. It's easy to check for leaks after filling with a water/dish soap mixture and a spray bottle around the valve for safety.
If it’s hot out then propane can easily reach pressures of 180+ PSI. I used to watch this happen on summer days with my 10,500 gallon propane trailer. Most tanks are set up to vent at 225 PSI if I remember correctly. Propane isn’t really a low pressure gas.
@@tenlittleindians trust me though, if you get hit by a blast of 180 PSI propane you will be having a very bad day and probably a very bad next few months. Sure, it’s low compared to an oxygen tank but it sure isn’t “low”.
@@stevenvanheel3932 Let me say the same thing, only in a different way. 180 PSI may sound low compared with 3,000, but imagine the damage it can do to your body. People have been killed by over-inflating tires, and that's a lot less than 180PSI, and the air inside tires is not super cold or super hot.
wow. Ive refilled those cylinders many times. Some more than 20 times, never an issue. With a single cylinder now hovering around $5 a piece this is going to be hard to swallow.
This is similar to "dont use car tires on motorcycles" in that any problems associated with doing what is not advised can contribute to injury. Unfortunately, both are never ending discussions because many in both the car tire on bikes and the using refilled tanks people have successfully done so for a long time. Interestingly, I havent heard one story from a soul in either group come out against the practice each swears by. Now, the question really is, is that a case of dead men tell no tales, a pride thing when something went wrong or are both safe and not as dangerous as we are all lead to believe? Im wondering with the gas stuff specifically, in what scenario could they "blow"? I mean, if the tank rusts or valve leaks, how does that casue a "blowup" scenario? Either way, I never particualry cared for pressured liquid turned to gas stuff and dont care to play with it either. If Im ever in constant need of propane, Im not messing around with refilling it unless it is something like the two heavy duty brands you show. Thanks for the video.
While I never intended to refill any non refillable propane containers, I wondered what the difference is between refillable and non refillable containers. Thanks for posting and clarifying this matter.
Yea, some things you can cheap out on with impunity, others not so much if you care anything about safety. IMHO you really should care about safety, both your own and others. Maybe you can get away with doing unsafe things for a while, but why take the risk if you don't have too?😁
some time back i ought a “mini” propane tank, looks just like the reg tanks used in a rv. but due to having to fit everything in a CJ-7. this little unit is great. larger than in the video but for just two days usage it is perfect. as it is refillable no problem. and no garbage filling tin cans.
I would'nt think of refilling a single use cylinder to start with. They're not safe when brand new if you ask me. The quality in this country has gone to complete hell in the last 3 years...
I wouldn't reuse them cans over and over for very long. Kind of the same deal with air compressors that dont have an air dryer on them. turn into rust buckets on the inside. looks fine on the outside.
If you are referring to a liquid substance you can see at the bottom of a 100# cylinder, it is likely what is known as "heavy ends" or, ethyl mercaptan. this is used to odorize propane to make it's presence detectable by the human nose since propane is actually odorless. Over the course of a number of years and many refills, ethyl mercaptan (EM) tends to settle out of the propane and collect at the bottom of the container. It only take somewhere on average of 1 qt. of "EM" to odorize 30000 gallons of propane. If you manage to get a bit of EM on your clothing, the best method of removing the smell is to leave it out in the sunlight after washing the clothing with soap and water.
It was like a 1/2 gallon of it in an empty tank. I inverted the tank and opened the valve and a pine green liquid started to come out, I stopped and left it in the tank not knowing if it was some kind of anti rust.
You make some good points. But 99.9% of those single use tanks do not get transported when refilled. It is almost impossible to fully fill any propane tank without a pump so the pressures are a little lower on home brewed refills. Most of that extra durability in the refillable canisters is to enhance safety when transporting. In closing I will agree some people refilling single use canisters should stop.
Um, no, once you have liquid in the tank it will go to it's ambiant presure based on whatever the temp outside is. I don't think a refilled rusty tank would just split open, it would develope a pinhole leak first. But, in the end, refilling a one - use tank is for emergencies only. Also, you can fully fill most containers by icing down the tank you are filling.
actually once there is any liquid in the tank the pressure is exactly the same at any pressure. you can look up propane pressure temperature chart and it will show you where the pressure is at with just one drop of liquid at any given temp
I used to refill the disposables. I did it for around a year, and then one day one of them swelled up like a balloon. That was enough to convince me to stop and go buy refillables. I was lucky it didn't explode in my face.
You do not need a pump to fill propane tank to full or actually over full. That's why correct procedure when filling portable propane tanks you have to weigh them to get the correct weight for your tank. If you didn't weigh you create a very dangerous situation because now your not sure if tank is overfilled and I have over filled 14.1 oz propane tanks before so I know it is possible to overfill tanks. Propane fluctuates with temperature that is why you need weigh to know for sure you are only putting in exactly the amount the tank is rated for of course you have to weigh the tank empty. The tare weight (just the weight of tank empty) and net weight is what is inside the liquid propane itself.
@@liv04soccer the thing is with a properly functioning bleed valve and proper fill procedure you can't overfill the container, if it's getting overfilled then the tank is malfunctioning or not designed to be filled. Most people dont know how to use the bleed valve to know when a tank is full though.
Air pressure tanks on compressors have a 7 year life. Beyond that the tank needs to be replaced due to corrosion. I've seen pictures of the aftermath of a pressure cylinder explosion and they weren't pretty.
I agree. Refilling also can cause fatigue cracking since the non-refillable ones never go back up in pressure once they drop below 100 psi or so (when there is no more liquid propane in them). Letting it go to near zero and then filling it again can cause an actual reversal of the load on the steel, like bending it back and forth.
Thanks so much for that. I tried to figure out a good way to explain how metal fatigue comes in with different grades of steel. The video seemed pretty boring already
I do use propane cylinders for the occasional plumbing. I have no reason to refill them and I wouldn't even know how. I guess that people who use them a lot would be tempted to refill them.
"I refilled these thing forty times and never had a problem." Gee, that's really great. Now what do you think the result will be when you Have a problem???
My result when I had a problem was simply that the canister leaked down prematurely. I discarded it and am now using another. Lost a little propane... that was it.
