Need Jerry can gaskets.

I have a couple of regular 5-gallon steel Jerry cans - gas cans. I need the rubber-looking gasket that goes under the cap.

Anyone here know where I can buy them?

Thanks,

--Bob

Good question. Did you check the usual places like Blitz, assuming they're Blitz cans anyway.

Thanks for the reply. I'll give Blitz a try.

If you can't find one, you might want to check Mcmaster Carr. You can pick up a sheet of thin "fuel resistant" rubber and cut a gasket out of it.

Whatever you get make sure it is wide enough to cover the vent hole. I've noticed a bunch of ppl selling gasket for cans, but they are really for the spout which has a thinner gasket so it doesn't cover the vent. BESRK probaly has the best idea. I haven't been able to find any good replacements.

I did a search and found some here:

I can vouch for this...

Blitz and several others use a different size neck hole than the old Military 'Gerry' cans.

Military type cans vent through a little hole just under the lip of the cap.
Gaskets for the military type cans need a gasket wide enough and thick enough to cover this hole, or your can will 'Drool' when shaken up.
('Legal Gas Cans' have a vent in the back side of the can)

Blitz gaskets don't cover that hole sufficiently to keep it from leaking...
Ask me how I know that...

My cans are "Blitz" brand cans. They have a small vent hole (I'm guessing about 1/16" diameter)under the cap gasket, at the uppermost portion of the hole.

The gaskets that came with the cans to go under the cap are wide enough that they cover this vent hole, which is sealed when the cap is sealed. However, the gaskets on the spouts are a little narrower, leaving the vent hole uncovered. Because of that, I can't use the spout gaskets under the cap, 'cause the vent hole will "weep" gasoline on the trails. Not a safe condition.

For the same reason, the suggestion of O-rings won't work -- they won't cover the vent hole.

I'll see what Blitz has to say tomorrow when I call them. If they don't sell them, I may be able to check out the local auto parts stores and see if I can get a couple of sheets of rubberized gasket material, such as is used for some diff cover gaskets.

Also, I seem to remember, from my younger days (a looong time ago), that some Jerry cans had cork gaskets under the caps. I'm pretty sure I can get some sheet cork gasket material about 1/16" thick -- that might work if I can't find any store-boughts. I can use the broken gasket as a template.

Cork is a bad idea since it degrades when exposed to gasoline...
the 'Cork' we had as gaskets had a metal foil liner on them...

Anyway, I use roll gasket material to make gaskets that actually fit my military cans...
Some kind of synthetic stuff, like rubber with a cloth weave built into it.
Seems to be working find now...

If you do Surplus (Junk) stores, you might just run onto a stash of those rubber gaskets once in a while.
I ran into a pile of them in the '80's and just recently ran out! Now I'm making gaskets instead of just getting one out of 'Da Box'...

Sounds about right.
Got it at the local NAPA store that caters to farmers and big trucks. Didn't work really good, but if you crank the lids down, it will seal...

.. you can also get the rubber thicker.. 3/16"? That might seal better against imperfections...

or yeah.. surplus store.

Not since the military hasn't used Metal Gerry cans in about 15 years, they are all plastic since the mid 80's...

Like I said, I got a gob of them in the surplus stores several years ago, but you don't find them much anymore....
TOO FAR out of date.

If it's a blitz can, the one down the page should work.
