A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Expect good resistance to engine and transmission fluids, petroleum oils and fuels, and aromatic hydrocarbons. Viton® (FKM) offers outstanding high-temperature capability 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). Verify compatibility before use with amines or ketones and esters. The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

Maintenance and OEM teams specify it across high-temperature process equipment, chemical processing, and oil and gas.
