Q-331 FLUOROELASTOMER 75 Q RING

QV70331 is an AS568-331 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 2.225 in (56.52 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.645 in (67.18 mm). In service, this quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Viton® (FKM) is specified for outstanding high-temperature capability and very low compression set at elevated temperature. Expect good resistance to chlorinated solvents, many acids, and engine and transmission fluids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in amines or hot water and steam. The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.

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

This item is sold individually under part number QV70331. Unit weight is approximately 8.41 g and nominal inside diameter is listed as 2 1/4 inch. Review your operating media and conditions against this specification before installation.
