Viton® (FKM) is specified for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Expect good resistance to petroleum oils and fuels, engine and transmission fluids, and aggressive chemicals. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It should not be specified for service in low-molecular-weight organic acids or ketones and esters.

Maintenance and OEM teams specify it across high-temperature process equipment, semiconductor equipment, and automotive fuel systems.
