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.
