Simma-Roller - Anyone replaced the rubber "gasket / o-ring" on the rotary processor drive wheels?

I have a Simma-Roller but the rubber "gasket / o-ring" has crumbled away.
Original piece was about 3/16' x 3/16" ~ 3" diameter.

Thanks in advance for the any solutions.

All the best

I haven't addressed this specifically, I have found large gaskets for old canister oil filters at farm and tractor supply stores that I have fitted around tanks.

Great Idea! I will give that a try.
Thanks
