I cut mine from rubberised cork sheet.

I cut mine from rubberised cork sheet too. But I always leave at least an inch or so empty at the top.

Re: Petrol tank cap gasket

I use a couple of things depending upon what is available at the time
The absolute best was 75% teflon sheeting which is a foam. slightly harder than a thong rubber ( the ones under your feet for those with funny minds ) which I used to get scrap fom a local factory
Next was cotton insertion buytl rubber , but it too comes in a couple of densities and it must say "petrol safe " or something similar

Down here you can not use cork sheeting unless it is whole cork because the solvents that get put in out fuels ( which are nothing like petrol ) attack the glues used on ground cork sheeting even buytl cork sheeting and they crumble away after a time .

I found leather to provide the best result after trying various other materials....Ian

Re: Petrol tank cap gasket

As some mentioned here..a piece about 3mm thick leather does give the best results

Re: Petrol tank cap gasket

I am using a viton flat flange gasket ring and this is working well for many years already. Leather dries out in months and cork shrinks quickly is my experience. Really happy with viton and can recommend.
In NL we can buy these at technirub.nl at 6 or 7 euro a piece.
