Viton® (FKM) is valued for outstanding high-temperature capability and very low compression set at elevated temperature. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in amines or low-molecular-weight organic acids.

Common environments for this compound include high-temperature process equipment, chemical processing, and oil and gas.
