Viton® (FKM) is specified here for very low compression set at elevated temperature and industry benchmark where nitrile reaches its thermal limit. The material holds up against engine and transmission fluids, aromatic hydrocarbons, and aggressive chemicals. Continuous operating temperature is published at -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 aerospace, chemical processing, and oil and gas.
