An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists petroleum oils and fuels, chlorinated solvents, and aromatic hydrocarbons. Viton® (FKM) is known for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where ketones and esters or hot water and steam are present.

Typical settings include automotive fuel systems, aerospace, and high-temperature process equipment.
