john minchin Posted August 29, 2021 Report Share Posted August 29, 2021 The red seal in my (standard) petrol cap has seen better days. Using a vernier the spec is approximately as below, it is currently a red fibrous material as far as I can tell and it sits in a square section grove. Internal diameter 53.5mm External Diameter 62mm Depth of seal 4mm My basic question is where can I get one ? They are not listed as a separate item in my spare parts book. (I can not find it anyway).

john minchin Posted August 31, 2021 Author Report Share Posted August 31, 2021 Thank you, that seems like a good solution. I feared that an O ring may fall out but if others have used it that'll do for me. Quote Link to post Share on other sites
Ian Vincent Posted September 1, 2021 Report Share Posted September 1, 2021 FWIW, I made my own from some cork sheet that I had lying around. It seems to work. Rgds Ian Quote Link to post Share on other sites
