Q-157 FLUOROELASTOMER 75 Q RING

The QV70157 is an AS568-157 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 4.487 in (113.97 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 4.693 in (119.2 mm). This quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

The material holds up against chlorinated solvents, engine and transmission fluids, and petroleum oils and fuels. Viton® (FKM) is valued for outstanding high-temperature capability and very low compression set at elevated temperature. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in amines or low-molecular-weight organic acids. The profile itself contributes two sealing bands per contact face rather than one and lower compressive load required to achieve a seal.

Common environments for this compound include high-temperature process equipment, chemical processing, and oil and gas.
