I'm being cheap (frugal), so bear with me. It's the gasket for the
pump on a 1 gal. garden sprayer, as sold at Wal Mart. I recall the
complete rebuild kit is about $5 but I just need the one large gasket.

It's rubber or some type of synthetic, although not shiny like
neoprene. It's roughly 2 1/8" OD and 2" ID and 3/16" thick. I
thought about turning a square channel in a piece of board with my
lathe and then filling that with silicone glue to mold a gasket, but
the silicone probably wouldn't hold up. My recollection from a couple
of years ago was that the local hardware store (which is pretty good)
didn't have an O ring that came close in size.

What other rubbery materials are easily obtainable to cut or form a
gasket? A sheet that I could cut with a pair of scissors or a razor
would work fine. Or a strip that I could form into a circle and super
glue into a ring would also work. What am I looking for guys?
