Clear vinyl PCV hose

I looked through several chemical resistance charts, all agree that they can't agree! LOL

Some say excellent, some say fair, some say poor, some just skip the test.

There was some discrepancy on "aromatic gas" and "non aromatic gas". I suspect all pump gas is aromatic, which had more "fair" to "no" ratings than non aromatic.

If I were to use vinyl tubing for gas, it would depend on the application. If it were for transferring, something I could see, not near any heat or ignition sources, not left with gravity or siphoning flow possible, then yes, it would probably be OK.

But I would hesitate to use it for a permanent installation on a piece of equipment. Especially if it were near the engine or heat source, or clamped to a fitting that could transfer engine heat, or leakage could go undetected.
 
Hello Steve@Advance,

I would not hesitate to use it as a gas line. Of course any gas hose SHOULD not be ANYWHERE near a heat source!

I would not use it, even though it may be
rated for it. Use proper rubber fuel line
as it has carbon in it and will keep fuel
transfer lines properly grounded to keep
static build up down. May not be a problem
on some applications, but better safe than
sorry. Black fuel hose is also heat rated
for under hood temps.

Whut he said... It will melt RAT NOW from a flame. It takes quite awhile to burn thru the proper rubber line made to handle gas on an automotive application...
 
I think what you are asking is vinyl pvc hose impervious to gas. The answer is yes many weed trimmers, chain saws,
lawn mowers, generators, came new with it on them.
 
Thanks for answers. Maybe I should tell application. I have an old visible (gravity flow)gas pump. The fittings that come out of the tank and connect to underground tank have a about 8" that have to use a flexible connection because when put together they don't line up good. I therefore can't hard pipe all the way. I have been using rubber hose but every 2 or 3 years it deteriorates. Just wondering about this clear vinyl tubing being better.

You need to post a pix and research this for a one and done fix...

What size tubing does it take ?
 
Vinyl would probably work for that application.

A better option would be neoprene hose. It can be bought at the better auto supplies, those that handle truck parts. Used for fuel line, tank filler, vent hose.
 

My problem is the pipe I need to put the hose on is 1 5/8" and I can't find anything except rubber in 1 5/8" ID. The vinyl I find is 1/4" ID and I think I might be able to get it on by heating it in hot water. Anyone's thought?

No way on earth you going to get 1/4"I.D. anything onto 1-5/8"O.D.

might want to visit McMaster-carr and look up fuel hose.
 
Lowes sells it in their plumbing dept. I have used it for fuel and hydraulic oil in my log splitter. Works for me. Lasts for single digit years so far. No end in sight.

Well they have 1 1/2" but it is reinforced, recon that would stretch enough? I
 
The clear plastic hose will work for a little while but it gets hard
and stiff. With fuel oil it is even worse. Gets rock hard in a few
days. Get the right stuff.
 
My main application was the 1" line from my hyd. fluid sump to the hydraulic pump inlet on the wood splitter I built. I wanted to see the fluid level being fed to the pump. Been 3 years now and no problems. Haven't checked it to see if it's rigid. If so no biggie as neither end moves.
 
I dont think it is rated for that use but I have tried it with both fuel and oil on temporary set ups. As one of the other posters said it gets hard as a rock pretty quick. How big an issue that is would depend on how much moment there is in the application and where it is used.
 
Forget PVC.

Just about every auto parts and hardware store sells Tygon fuel line. It comes in a few different sizes and colors including clear..

Tygon hose can be used with ethanol laced fuels and will not harden over time..
 

First, this is the most complicated way to post a photo I ever saw. I doubt I could do it again without going through the same trial and error method.
Now my post. I used the clear vinyl reinforced. Got 1 1/2" ID and was able to get it over the 1 5/8" pipe. I could not find any hose 1 5/8" ID that is gas resistant. In fact I found very few place to get 1 5/8" ID at all. This will have to do.
