Busch O-Ring, 53.57 x 3.53 mm - Viton Part# 320275
This ring is made from Viton, which is also called FKM or FPM. Because regular rubber rings can fail when things get hot or oily. Viton is different. It is tougher.
Here is what Viton brings to the table:
High heat resistance: Works great from -30°C up to 200°C .
Chemical fighter: It stands up strong against oils, fuels, solvents, and many acids. Regular rubber would swell or crack .
Weather and ozone proof: Viton does not dry out or crack from sunlight or ozone exposure. It stays flexible for years .
Great for vacuum: Viton has very low gas permeability. That means it holds vacuum pressure better than many other materials
