Expect good resistance to aggressive chemicals, engine and transmission fluids, and petroleum oils and fuels. Viton® (FKM) offers very low compression set at elevated temperature 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). Applications involving hot water and steam or amines call for a different compound. The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

Common environments for this compound include aerospace, automotive fuel systems, and semiconductor equipment.

Reference part number QV70241 when ordering; the item is sold individually. Unit weight is approximately 6.2156 g and nominal inside diameter is listed as 3 7/8 inch.
