Viton® (FKM) is specified here for excellent resistance to compression set and permeation, very low compression set at elevated temperature. The material holds up against engine and transmission fluids, many acids, and petroleum oils and fuels. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with amines or ketones and esters.

It sees regular use in aerospace, automotive fuel systems, and high-temperature process equipment.
