Mk1 oil filler cap seal

[Lagnakeil]

Hello
can anyone tell me where I can get a cork gasket ( or other) for a 3 prong oil filler cap?
THANKYOU

Doesn’t this work?

Thought the seal diameters were common between 1&2.

sorry if that’s not the case though.

I had this problem also , the mark 2 cork gasket does not fit a 3 prong cap, my 3 prong cap had a rubber seal fitted, I took the measurements of it and found an equivalent rubber seal to replace it , off eBay , don’t leak from there anymore. Graham
