Hardware Store Hot Rod Parts - Cheaper And Stronger Than The Real Thing 

So does rubber

depends what kind of rubber, natural rubber yes you are correct, Buna N no same stuff every oring is made of in your fuel system., besides viton or fmk. @@tkello001

The cheap shower head hoses definetly, and ever for a generic water hose they're crap, deteriorate in a year, very tear-prone, no tensile strength, and very prone to collapsing when bent

I was about to say the same thing. You could use them for heater hose, but not fuel or oil.

​@@tkello001not all rubber

That's certainly one way to do it. Another IMO more user friendly option would be to use a 12V solenoid valve controlled by a switch inside the vehicle so the coolant flow can easily be turned on or off with the flip of a switch. Just make sure to power the switch with a circuit that's only active when the key is on so the battery can't be drained by leaving the switch on while parked!

My brother did similar in early 90s for his A50 Colt

I know you prob meant a brass ball valve, but the first image that popped in my head was an 1-1/2" PVC ball valve, and that cracked me up for many a reason

I like cheap!

Way cool, Thank you.

We used PVC for turbo cold side on my wife's old minivan. We did this for fun before junking it but it held 15psi+ boost.

Yep we used only swagelok fitting on stainless hardlines for particle accelerator cooling systems at around 350psi nominal pressure.

You ever do LADWP peaked units in Long Beach ca? The LM 6000 is used a lot in peaker power plant units… impressive machine and the plant is easy to build.

Never did work in Long Beach, but did units all the way from San Diego to Redwood country, The GE peakers are very compact and reliable engines, and I have tested them all over the world. The LM5000 that preceded it didn't have as good a reputation, but I tested one in Modesto that ran trouble-free for every 17,000-hour service interval for years. The newest peakers have ramping guarantees to reach baseload within 10 minutes of startup. I saw one on a flatbed in CA one time, it was the size of a pickup.

lol, a high up (big-wig) got salty at me for asking what "swagelok" as good for and did (3 years after I first asked him) 🤣🤣🤣

The lines will hold, but not if the end is cut off and replaced with a hose clamp. That's why he said to only do it for low pressure.

Chemical breakdown due to petroleum exposure isnt considered by water line manufacturers.

Yep. PTFE braded lines have a working PSI of 300 and are burst rated at 1,000. These will work on anything fuel delivery related in the automotive world.

I'll give you one guess as to what most fuel tanks are made of or lined with if they are stamped metal. You can literally buy braded 6AN size PTFE fuel line. There is absolutely nothing wrong with using this line as a stock, it just needs sized fittings that fit appropriately. It would take some bench testing, but I'm betting that an Earl's barbed insert and screw down fuel injection fitting would work without any issues.

I have seen many of these supply tubes leak, especially when they have been bent into a hard crimp for several years.

It's really not, and factually incorrect. PTFE is used in high pressure situations all the time. And is widely used in the automotive industry, especially in high pressure fuel lines.

More like big box

Lol they won't hold the pressure of a p.s pump maybe good for the return but nothing more They are not PTFE so they are no good for fuel and I won't even trust them for oil even less hot oil

Very cool !

Very cool history.

80 PSI that's wild. The tenants could be breaking records for fastest shower ever.

Is there no valve in the complex that can lower the flow and hence the pressure?

It is not the hose that will fail, it is the hose tail/clamp that will leak. Remember there is a lot of vibration when running. Like he said, it would probably be OK at higher pressure, but would you take the risk?

@@auteurfiddler8706 the problem with that approach is under low use the pressure will climb back up to 80 psi. And under heavy use like in the morning when many residents are taking a shower the pressure will drop to really low levels with just a trickle at each faucet. A partially closed valve is not a pressure reducer, it's a flow restrictor. A proper pressure reducer will modulate internally to maintain the correct pressure regardless of the demand on the water flow. Though, 80 PSI is really not that high. It's at the upper limit of most faucet recommendations but well within the specs for the pipes and other plumbing. The building I service has 65-70 psi from the booster pumps and I see no issues with any of the showers, sinks or toilets. Haven't had any of the lines burst from pressure

​@@tilliesinabottle80 psi is NOTHING. I have 125 PSI in my house from city water, and I know a plumber who told me of an area where they have 175

@@rheidtech if you're going to use PTFE line, they make a fitting similar looking to the AN stuff.

People don't use them because they are not PTFE and won't last a week in presence of gas much like is previous hose that probably failed because it's not rated for ethanol fuel

You have any pictures of them?

@@andrewtesti not currently but maybe one day here ill make a quick video and put it up

Yepper works well

I worked at a shop where an old Corvette came in, with the tri power setup. The new (aftermarket) fuel line he put on leaked. So he bought another and just assumed it was used error. After the second fuel line setup leaked as well, I told him I could make it with brass unions and stainless hard line. I shaped the brass fittings with a grinder and polished them, and also polished the stainless in between. It looked really good, and didn't leak a drop. Several people at car shows asked him where he bought his fuel line kit. And I probably ended up making half a dozen stainless and brass setups

@@ryurc3033 Very cool

Tavo?

Tight arse Valiant owner

Or ass for the septics.

And that's a good thing. DON'T use this hose on fuel. The only hose you want to use on fuel is carbon lined. Otherwise static builds up in the hose and arcs through the liner to the stainless steel. When you use carbon lined hose rated for fuel use, the carbon is a ground on the ID of the hose so the fuel can't build up a static charge. That's why SS braided hose got a bad rap for making garages sell like gas when cars are parked. Without the carbon they end up with microscopic weep holes in the liner.

Tight Arse Valiant Owner TAVO it’s a Aussie thing

Lol pvc will melt in gasoline man lol

Teflon insulated electric cable used in RF, or high heat applications melts at a much higher temp - soldering iron will not effect. We tested a sample (taken from semi-rigid coax) in a gas chromatograph (think that is what it was) and it started to de-gas at about 900C - and was still intact above 1200C. Did not melt. So what is special about this version of PTFE?

ptfe/teflon is commonly used in 3d printers that print up to around 230C as a tube that goes up to the nozzle and used to be used for holding the heat block itself(cheaper to machine so hobbyists and tinkerers devised plans they shared and they were sold a lot). in the hot ends where it touches the nozzle(non "all-metal") the end of it goes bad over time(blackens) but it still lasts a long time. it's way beyond most underhood temps. however you have to remember that if you heat it too much it will outgas a toxic gas - it's not really that much of a problem if you don't get it basically on literal fire but in 3d printer circles people freak out about it often.. even if they cook with teflon cookware on a gas stove. the actual practical problem with the 230-240c softening/blackening limit is that if the tube doesn't seal against the nozzle well enough then the hotend starts to leak through the threads, one of the common frustration reasons why you'd find 3d printers at the curb. a really nifty material for tinkerers. in the blocks that you can machine it you can cut in threads too.

ALL of those magical flex lines are prone to being poorly installed (twisted on normal install). don't ask how I know. and majority loves to be eaten by ethanol/ethanol stacking.

What's an axle key?

@@tommymac3029 Axle shaft keys or just "axle keys" are essential pieces of hardware when keeping a drive wheel tight against a revolving shaft. The key fits into a keyway, the rectangular slot that is milled into both the shaft and hub. The familiar sunken axle shaft key is always square in cross-section, although it may have rounded or bevelled ends to fit a rounded-slot axle keyway.

Oh. Thanks. I'd call that key stock to fit into a keyway.

whats with the large spaces in this comment? like something was redacted?

​@@Biokemist-o3kIs that similar to a woodruff key ?

Glad to see at least one other person realized that static blows holes in non-carbon hoses.

What was it that you bought, Water line hose for the fridge?

elaborate more what video?

I was going to call a bluff . But it make sense. 👍

They don't want this hose on fuel lines because static charges build up and discharge through the inner liner to the steel braid. For fuel use, you have to use carbon lined hose so the inside is grounded. If the fuel can't build up a charge, it can't blow microscopic pinholes though the liner.

Bullshit because they don't resist fuel they are pvc hose you won't find PTFE line with end for this price ever lol He even just posted a video saying he was wrong lol

Yup, all the major brands say pvc or nylon. Nylon is ok for gas & oils, pvc is not. If you have doubts, wipe on some acetone. Nylon & teflon will laugh, pvc will dissolve.
