In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists aromatic hydrocarbons, chlorinated solvents, and many acids. Viton® (FKM) offers outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It is not the right choice where hot water and steam or low-molecular-weight organic acids are present.

It sees regular use in chemical processing, semiconductor equipment, and oil and gas.
