FKM Viton Rubber Gasket Washers

FKM Viton Rubber Gasket Washers is a Premium rubber elastomer resistant to chemicals and useful for sealing against acids and lyes of any

concentration, solvents, aliphatics and aromatic hydrocarbons, Freon 12, oils and fats and gasoline

It has excellent resistance to weathering and ozone. Premium Viton rubber sheet has extraordinary resistance to heat with resistance also to

low temperature and is self extinguishing, FKM viton rubber gaskets has excellent compression set in compression at high temperatures.

It's extremely resistant to alkalis, including oxidants.

FKM (Viton™) comes standard in a 75 +/-5 Durometer Shore A Hardness with a light cloth finish. FKM (Viton™) is rated for use in applications

involving temperatures up to +450 F constant or +500 F intermittent. FKM (Viton™) also offers excellent chemical, gas & oil resistance which

makes it a good choice for a variety of applications.
