Are you close to a Cat dealer? Cat has about every o-ring ever made, and in different materials, like Viton, Buna, poly, Silicone, floro, etc. Ask the parts guy to look them up in "similar parts". He should have a compatibility chart, to suggest what materal to use, but, usually buna will work. They actually have o rings so small, you can hardly see them, clear up to about 5' in diameter. And, in Metric, also.
