As a material, Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, outstanding high-temperature capability. It resists chlorinated solvents, aromatic hydrocarbons, and engine and transmission fluids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to hot water and steam or low-molecular-weight organic acids will shorten service life.

You will find this material specified across oil and gas, high-temperature process equipment, and automotive fuel systems.
