[Milsurplus] Source for Leather Washers ?

[J. Forster]

They are cupped by design. The cupped seals act as check valves.

Did you cut the leather flat stock into a washer shape, soak it in water
until very soft, then push it into the cylinder?

Also, any good supplier of small pieces of thin (1/16") leather sheet. I
need a piece about 6" x 6". There are on-line suppliers, but they seem to
sell mostly whole cows.

Thanks,
