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

As a material, Viton® (FKM) is specified for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. This material stands up to many acids, aromatic hydrocarbons, and petroleum oils and fuels. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service.

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