Q-032 FLUOROELASTOMER 75 Q RING

Part number QV70032 is an AS568-032 black Viton® (FKM) 75 Shore A Quad-Ring built to an inside diameter of 1.864 in (47.35 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.004 in (50.9 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Viton® (FKM) is known for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. This material stands up to aromatic hydrocarbons, petroleum oils and fuels, and chlorinated solvents. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in hot water and steam or ketones and esters. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and lower compressive load required to achieve a seal.

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

QV70032 ships individually. Unit weight is approximately 0.757 g and nominal inside diameter is listed as 1 7/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
