Looking for petrol tap-gasket -> "Jota 120 °"

[Thomas aus LAU]

On Matthias Jota 120 °, built in 1982, the riveted petrol taps are leaking.

I filed down the rivet head, drilled it and cut a 3mm thread into it instead of the rivet.
Amazingly, the compression spring (on the right in the picture) that is mounted on the screwed version as on the Jota 180°, built in 1981 was missing. I have now added such a spring for better sealing.

Is there a replacement for the 4 x perforated seal D = 21 - 22 mm, 2.2 - 3.0 mm thick?
I haven't found anything about this in the archive.

Seals from R100 or Suzuki 1100 could fit if you close the 5th lower hole.
I think the raised edges around the holes are important for a good seal.
If necessary, we have to look for gasoline-resistant sealing material of the right thickness and mill the recesses.

Thanks for tips from Thomas aus LAU

My brilliant mate CMac made a little jig to replicate these himself from rubber sheet. I've borrowed it and made some of my own, they work fine as a flat gasket and do not require any raised edges (the tap body has some already).
Having said that, I'm sure someone will be along to say you can buy them from a certain shop for $1 each!

You right Steve,
Pretty sure Bevel Rubber sell them but they are not $1 each...

Thanks, right size, right number and position of holes - but flat
We can easily manufacture flat ones ourselves. I use used paper drills that you get (almost) for free in the next bookbindery.
