This material stands up to many acids, engine and transmission fluids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) delivers very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where amines or ketones and esters are present.

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