How to Easily Install a Schrader Valve on any Can to make It Refillable without Drilling or Torch. 

Where did you get the 3oz fill bottle with the PERFECT cap / valve fit?

@@Thinker2-truth it looked just like the one I have, from Shaklee multi-level sales group around 30 years ago. Made from high-density, high-molecular weight, polyethylene blown as shown. Great little squeeze/squirter. The ones he offered via amazon are the thin wall delicately handled version, they do not have a flip to dispense top either.

@737mechanic wd 40 separates when it's mixed it's cloudy I noticed yours was clear means it's not mixed just a FYI cool video

I have a vintage JenniCan that you can open the top to get your product in easier. It will be nice when they become popular again. Just had a look and while there are dozens of DIY mods and through he valve refill options I was happy to see that there were at least 11 contemporary refillable systems showcased and they seemed to have removable tops that let you fill them easily.

Galaxy brain move holy

Thats all. Everyone needs a lathe.

It wouldn't really need a lathe you could easily cut it with a hacksaw spin it in a drill with a piece of sandpaper.

More have a drill or a torch. Very few have a lathe ???

@@PeterHernandez-lg2eh Get a lathe, problem solved.

Was thinking same thing.

the tire valve stems are made of rubber that is not oil resistant. the oil inside will eat tru the stem and will shoot the valve out, hopefully NOT in your eyes.

​@@west_park7993 the sealing ring doesn't retain the stem, it's metal and gets screwed into the assembly. If it deteriorated, it would just start leaking . The solder letting go is the risk of the valve going projectile.

@@west_park7993 Those are made for cars. Get some made for big truck rims and they will be all metal.

the corporations aren't making any more money, the dollar is losing it's value. LOL

Turn that gallon can over to the side with your nozzle on the high side. You can pour it out with a nice even stream.....your welcome

The newer refillable spray bottles dont last all that long.....Chyna made

@@safetyharborfirearms I AGREE, I HAD ONE LAST 2 WEEKS

Mine kept falling over and leaking WD all,over the place.

I find the pump bottles to be spotty as far as quality and dependability. I use a Vaper pressurized spray bottle, but its a bit much, when sometimes I just want a little squirt

Exactly

@@ljbellinger True, but you have to make a larger hole in the can. I think you can spin it in a drill and grind off some brass with a file. It is small enough to work without a lathe.

@@AM-dn4lk Yes, with no Lathe - you read my mind. A punched hole prevents drill swarf inside the can. I knew about this idea, but it was the 100psi that prevented me from doing it. I have many Cans of half-full WD 40 - with no gas inside the aerosol! It happens a lot to WD 40 Cans that I buy.

@@peterduxbury927 PB Blaster is my notorious gas fail with lots of penetrate product left. Great fix!

@@peterduxbury927 Just take the spray nozzle off and use an air blower in thru the outlet tube on your cans that still have content in them😎

​@petermurphy3354 Yes sir, especially that rubber tip blow gun, works on so many things...

Hi Niki! Although it seems to be a good idea, it isn't. That method does work with compressed air, which is sort of OKish on large cans, although its really tedious, because you have to bring the can up to pressure very often. On small cans like the air wick stuff, it doesnt work at all. The reason is pretty simple: spray cans normally are filled with the product you want to spray plus a liquid, that has a very low boiling point, so it is - at room temperature and under normal pressure - already a gas. Compressed to 3-5bar however, it is still a liquid. A good example for such a substance is propane gas, which is indeed used in spray cans as propellant. In the propane tank you might know perhaps from a BBQ or camping stove, it is under pressure and liquid and when you release it from the tank it evaporates and becomes gas. The benefit is, that as a liquid, it takes much less space, than as gas (comparable to water, that creates an enormous amount of steam as it boils) Now this effect is used as well to propel the product out of a spray can. When you press the cap, the pressure squeezes out the product as well as some propane gas (that is why the vapes are flammable even if the product isn't). The trick is now, that as you loose pressure, liquid propane will evaporate, until the initial pressure is re-established. In simple words: the propellant gas is practically a built-in compressor, that keeps the pressure high until all the propellant is evaporated and hopefully all of the product came out of the can. With compressed air, you have only a limited airspace over the product under pressure. When that pressure is used up, you need to refill the compressed air. That is why it works soso with larger cans. With an air wick you have perhaps 1-2 ml of air under pressure. That is probably even not enough for one single spray. Sorry for popping your dreamubble and sorry for using the metric measures. Being German I'm not used to convert to imperial. Cheers Andreas

yeah but probably better use a car tire foot pump as getting it up to 80-100psi with a bike pump will be a challenge ;-)

@@g4z-kb7ct I have both a floor pump and a frame pump but a foot pump would make it hands-free so that's a great idea.

I think the hissing sound you are hearing is the sound of insects outside (cicadas and such), not compressed air.

That's my concern on it. One time I bought a "fillable" compressed air can (it was designed to be refillable, with a standard valve stem on the bottom). Nowhere on the can or the packaging did it give the maximum pressure rating of the can, so I never used it (seemed a highly unsafe item). Either couldn't find the company or couldn't get an answer from them, and whatever store I bought it from (maybe Staples?) would have been clueless on it too. These days I would have reported it to a safety agency or something like Consumer Reports.

If you can operate a lathe safely, you're probably safe to handle a little compressed air.

Stop trying to parent idiots karen. These people do dumb sht for stupid reasons because they just dont care.

Those cans are rated from the manufacturer to hold much more psi than most people's compressor can make. My compressor kicks off at 180 psi and it will not explode a brake cleaner can. Id be more concerned with knocking a hole in a can that has pressure in it (by accident)

the problem with refilling those refrigerant jugs is the metal is so thin and it will rust on the inside and can explode and kill you. When they have refrigerant inside they cant rust but will with air inside.

@@jimthvac100 Only fill with air that has been thru a desiccant, drying out the air ... ought to have one of those on the air compressor anyway. on the intake side.

You can always make some homebrew to save a few bucks. Like a mix of atf with a little gasoline for penetrating oil. It won't be as good as wd or kroil but it would be 1/10 the price.

Chuck it up in a drill and use a file .Brass is pretty soft . Good Luck

See my post on this, agree with what you say, neccessity is the "mother of invention"

I spend 5 dollars when I have plenty of free empty spray cans? Once modified they work better than spray bottles. Besides those spray bottles end up leaking once the seals so bad.

Fair idea for easy applications, but would t work for those times where cramped space requires you to have the can upside down and/or use a straw. Spray bottles don’t generally work upside down because the intake straw is then in an air pocket, and ice never seen a spray bottle that accepts a straw on the nozzle. …though if you know of a brand/style that does accept straws in the nozzle please let me know because I’ve got uses for a setup like that!

EVERY Spray bottle seals or plastic gets brittle with time. This is a great refillable solution for solvents, acids and even weed killer!!!!❤❤❤❤

When I was a parachute rigger we used mil-spec "Leak Tech" which was taxpayer funded liquid dish soap in an extravagant guize... Nothing like a few hits of 100% aviators breathing oxygen when there's too much red in the white of your eyes!

I found a 737R Impact Rated Precision Action Wrench. Is that what you mean?

No swarf from drill in can to stuff up spray nozzle

@@johngibson3837 I'm jealous I didn't think about that. But that's one of the few good things about U-TUBE, the sharing of ideas. Great thinking John, you the man.

The dispensing valve in the can has a low service life, intended for single use and so, built cheap. It is not serviceable. The can will not "last a lifetime" unless you mean a few refills. Placing the charge valve in the base pressure dome is a stupid idea, but not for the fluid immersion issue, which the valve will always suffer, be it vapor of fluid in a pressure charged can. Drilling into the can is a messy stupid idea. Pearce the small hole and open up by roll forming using a hardened steel rod (screwdriver shaft) is far superior. The hole only needs to be 1/4" diameter if you buy the cheap copper hose tail Schrader fittings. (HVAC industry) Certainly not agricultural tyre stems.

About the air pressure limit? If I ask my son to put air in it, forget it. I rather use a bicycle pump, air compressor is too dangerous, WD cans are stronger than others.

@@stanwooddave9758 thanks Stan appreciate your words

I know, Thats why I was wearing safety glasses. You should watch the other 2 videos I did pressurizing them to failure.

@@737mechanic Aha...the nozzle popping off is a nice warning shot that things are turning sideways. Seeing things like that in a video might help somebody to react fast enough after they notice "oh weird, that fixture just popped off..."

@@blueskyhigh420 Hopefully they don't have a compressor that builds that much pressure.

Couldn’t you pull a vacuum on the can using a set of gauges stick your refrigerant line in the WD40 can?

genius dude ty! already ordered 10 lol

Yep... the perfect source for schrader fittings. The slim brass fitting on a copper tail form makes it easy to solder in securely (without specialist tooling) and not stick out like dogs balls. HVAC trade wholesaler is the place to go.

@@homerogonzalez2909 Naaa.. just trade and craft.

​@@rchighfield1 - Yes, BUT... You will leave residue from your refill in your A/C service hoses. Not ideal, IMHO. Especially if you are filling the spray cans with something that can attack the inner hose. Still, if you have A/C gauges and hoses, you can re-pressurize the spray cans with NON-OXYGEN gas (you know which kind!), and eliminate the explosion hazard you get with compressed air. But NEVER pressurize cans with straight Oxygen!

Be aware. if you overpressure it the schrader valve could explode out of the can like a bullet, especially if you accidentally drop it and the can lands "just wrong". the can itself has been weakened buy introducing a hole into its structure. Hacks like this can be very dangerous. much safer to just buy a pressure pot for your compressor or a pump pack designed for the purpose.

@@DeveloperChris You're a democrat, right?

I also bought refillable bottles about 20 years ago or so. My spray heads leak and need replaced. Where did you find replacement spray heads?

I notice the main problem with these spray type cans is the plastic spray nozzle becoming inoperable due to clogging and/or mechanical failure where it attaches to the check valve. I have yet to find a solution to fix the functionality of the nozzle/valve or safely recover contents inside the can???

well said brother. well said.

​@@bryanbeddingfield5489I agree. I only have a mini lathe but the amount of things I've made and repaired with it over the years, I sure wouldn't want to be without it now. I'd love an AC/DC TIG to tackle aluminium but they are expensive to buy and it's a real skill to master I know. I have a MIG and stick welder for the other metals so kind of get by.

There's not much you can do with a lathe or a mill that you cannot do with a file and some determination. Is it practical for someone who is spoiled with a lathe and mill, no. If you own a wood splitter you're not going to split a seasons worth of wood with an ax, but if not, you don't have to freeze to death. To scrape a little bit of brass off with a file would probably take half the time that the rest of the project takes. Probably half the time setting up and turning down. It doesn't take a Skin-o-matic 5000 to skin a cat either, there's a bunch of ways.

@@ricoloco2803 I was that guy, struggled with a file etc to get the job done, then I bought a lathe and mill and learned how to use them, that in itself is satisfying. At the end of the day, the moto 'right tool for the right job' applies for good reason.

@@ricoloco2803 How long would it take you to "Machine" a 5/8ths keyway in a solid 6" stainless shaft ? Thanks, you sound very knowledgeable, and talented.

I also worry about using compressed air to pressurize atop fuel. I advise against it, and definitely ​NEVER pressurize cans with straight Oxygen! Nitrogen (for filling tires) is available at some service stations. CO2 also works, and for some purposes, injecting some Butane would be a good way to pressurize. Using air also runs the risk of putting water into the can, which will rust through fairly quickly if there is any free Oxygen in the can.

My favorite DIY homemade concoction to replace the expensive liquids intended for breaking away stuck or rusted fasteners, is exactly a mix of either acetone or MEK and synthetic ATF+4, around half and half, but could vary between 60/40 to 40/60, depending on how fine or coarse are the stuck threads... Way better than "PB Blaster", "Liquiwrench", "Kroil", "Würth Rost-Off", and of course the very mediocre WD-40...

​@alfredomarquez9777 Try adding some kerosene to the mix (I've seen it called Ed's Red before). I use 1:1:1 and it works a treat.

What's the atf/acetone mix for?

@@jamiepayne9801 Homemade Kroil

LOL, Those are cicadas and at this time of year, they are loud.

Yes, I posted a link so you can order one. :) Or you can get creative and figure out one of many ways to accomplish the same goal.

Or drill press, file, or grinder.

I was a little concerned about this too

The only reason I wanted it centered was for neatness. Yes, you could make the hole whatever size you want, the reason I made it smaller was because I didn't want to heat up the can any more than I needed to so I didn't melt any of the internal seals and to make it easier to solder.

scary

I use a cardboard box and a clip on inflator and raise the pressure remotely at the regulator. For me the box was less about safety and more about cleanliness in case of a blow out

You should watch my other 2 videos where I pressurize them to failure.

Always wear safety glasses and other safety gear to protect your eyes and face if some solvent or other object happens to fly from the can!

Correct, you never want to pressurize anything with oxygen. Oil and pure oxygen is an oxidizer and can combust. Thats why you want to use air from a compressor which is 78 percent nitrogen. If it was unsafe to have oil and air mixed together, we would have fires all over the place. BTW they actually make commercial refillable aerosol cans that are meant to be pressurized with a common compressor so you can spray things like WD-40 and other oily liquids. This isn't a knew idea.

@@737mechanic ever heard of diesel engines? They operate on atmospheric air containing the same 78% nitrogen. Fire isn't the issue. It's the explosion risk

You're awesome dude. Hopefully, you can find more entertaining videos.

@@737mechanichow muck for 4 and the solder fitting

I was thinking the same thing. Engineering best practices try to avoid that kind of situation in vehicles, chemical plants etc. How much of a risk is it inside an aerosol can where there’s less chance of an ignition? I’m not sure. But it’s definitely something to keep in mind.

I don't think WD40 is going to be explosive like starting fluid would be, however it will burn. It would take quite a bit of heat to make it burn and smoke, but you shouldn't get anything like an explosion from WD40 burning.

LOL, Yes it is.

@@billharrison3174 I have tapped stuff that thin, you can't get a lot of purchase and you have to go slow but it can be done.
