Gas can leaks and gasket material

Postby Gunns » Thu Nov 15, 2012 12:15 pm

OK so these new safe gas cans leak like a sieve. The problem is I live in MN and if I fill one of these up and leave them in the garage, the gas travels up those nice safety pour tubes due to temperature differencs, then leaks past those nonfunctioning built in gaskets.

Does anyone know where to buy 1/4 inch hard like rubber gasket material so I can cut out my own to seal them?

Thanks

i got one of those at lowes last year. way over priced and it is the worst gas can ever! they seem like they are 3x more dangerous with the leaking and also the way the pressure builds up in them.

RJ,
You cannot have it both ways. If the container does not vent, then it WILL pressure up. If it has a vent to release pressure then it will send fumes into the surrounding space. In addition to being fkammable, gas fumes are also a CNS depressant.

ya your right but I do wish they had a pressure release that could be manually opened. Kinda like the older cans that you could open to increase the flow rate. On one occasion there was enough pressure in it that it looked like it was going to rupture the can. I probably shouldn't keep it in my shed with 50 degree temperature swings tho.

New cans also collapse when cold. I have a metal can I think I will clean up & use. A few years ago I bought on clearance 3 pkg of caps & spouts, old style. To replace ones we broke or lost. Wish there had been more. I don't care if gasses vent, my shop is well, um, " ventilated."

The flaw in the older cans was that the pressure relief would open when pressured up and vent the fumes into the air. This contributed to many fires. A simple wat to defeat this new annoyance is to puncture a pinhole in the top of the can. In the handle is ideal. This will allow for pressure to escape, but recreates the same fire hazard of the old cans. If you have just a couple of gas cans, then store them in a metal trash can outdoors, in the shade. The temperature swing will still occur, but the fumes will vent outside, not in the shed.

I installed a tubeless tire valve stem on a 100 gallon gas tank (before it ever had gas in it) and can equalize the pressure with a tap on the valve (just like adjusting the air in a tire). Or remove the valve and lightly place a cap on it. With just a cap it will stay clean and the pressure equalized. Works for water tanks to. There are other valves, but tire stems are easy and cheap to get. I have done this with six five gallon jerry cans, but they were new and just be very careful with the drilling, if they ever had gas in them.
A friend took it further and uses them to vacuum seal large containers such as 55 gallon drums. Swamp

Wow, vacuum sealed drums! Whodathunk!

Hey, gunns, what about auto parts stores for gasket material? Or hardware store? Even if they don't stock it, they can get stuff. Where I work, I can order ALL kinds of off, stuff I'd never stock.

I have a metal Jerry can and only fill it at the 4 gallon mark. Once every few months, I take it outside and open it up to release the pressure. I tried the plastic, self venting and it stunk uo the garage with gas fumes. That was a short lived disaster.

Just a note, if your garage is attached to your house please dont store gasoline in there. 35 years as a firefighter, I saw many garage fires, can't say exactly how many were caused by gasoline storage, but when the garage is attached it really makes fighting the fire and keeping it out of the house a lot harder. Try to keep it in a storage shed if possible away from the house. I know it sounds like common sense, but I learned a long time ago that common sense is like the unicorn, everyone has heard of it but no one actually sees it.

Good advice, my garage is unattached. I wouldn't store that much gas anywhere near the house. As it is I am still worried about it.
