Greaser spare part needed

[Miss Marple]

Does anyone know if it's possible to buy replacement rubber piston seals for the top part of a stern gland greaser? 4cm diameter. Mine has perished...

 

I have googled but can't find any.

Just to point out that I think that one is leather and if it is fitted centrally above the big washer with another washer above it you may well find that the edges can be bent down evenly all round and refitted.

It's definitely rubber and a proportion of the outside raised edge has rotted away.

Cut a circle of the correct size from an old tyre inner tube or similar source of rubber. Refit between the discs. Or a piece of leather from an old shoe.

You could possibly use plastic  from a plastic container but you would have to be very accurate with the size and cutting.

Even thick non corrugated cardboard would do at a pinch

I do have some leather I could use but it wouldn't fit properly as it would need stamping into shape I think. 😭

I'm trying one of your ideas. I had an o ring the right size so have glued it to leather. I'll wait for it to dry and try it tomorrow 😃

Well, that was a massive failure.

 

Back to the drawing board...

Try Ebay, I have sourced old pump washers on there before. For example this leather washer may fit https://www.ebay.co.uk/itm/265040470349?hash=item3db5a4a14d:g:mBwAAOSwL9hc3VOU
