I make gaskets for lots of things out of either roll cork or gasket
paper, depending on what the original was. I've even cut them out of
a paper grocery bag. Here, the original was probably cork or leather,
so cork is a good bet. The roll stuff is available in different
thicknesses, but most auto parts places only have one thickness. It's
probably okay for your use, since it's something like 3/32". Some
gasket sealer will keep it from leaking. (If the cover and the mating
surface are flat, just glue it to the side facing the cover. That
way, you can remove the cover with out damaging the gasket. At least,
that's the theory...)
