It resists petroleum oils and fuels, aromatic hydrocarbons, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is valued for long service life in hot, chemically aggressive environments and outstanding high-temperature capability. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving amines or ketones and esters call for a different compound.

Common environments for this compound include semiconductor equipment, aerospace, and high-temperature process equipment.
