Sounds like one of the rubber rings that are used on pinball machine's bumpers
and flippers. Lookup a pinball parts supplier's web page and see if that's what
your rubber ring looks like, then you might be able to get one at your local
pinball route/home gameroom supplier. They come in lots of different sizes, and
serious pinball collectors and maintainers replace them at least yearly. Even
most little towns have a place that maintains pinball machines.

(I have a couple of pinball machines at home for thrashing on when the bands
are dead. They give me something to take my stress out on besides pileups.)
