Q-037 FLUOROELASTOMER 75 Q RING

This quad-ring is supplied in AS568-037 black Viton® (FKM) 75 Shore A supplied with an inside diameter of 2.489 in (63.22 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.629 in (66.78 mm), catalogued under part number QV70037. It resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Viton® (FKM) delivers long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. The material holds up against engine and transmission fluids, aggressive chemicals, and aromatic hydrocarbons. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in low-molecular-weight organic acids or amines. The profile itself contributes two sealing bands per contact face rather than one and a parting line located away from the sealing surface.

Common environments for this compound include high-temperature process equipment, chemical processing, and automotive fuel systems.

Stocked as QV70037 and sold individually. Unit weight is approximately 1.0641 g. Review your operating media and conditions against this specification before installation.
