Q-382 FLUOROELASTOMER 75 Q RING

Part number QV70382 is an AS568-382 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 12.975 in (329.57 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 13.395 in (340.23 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Viton® (FKM) is specified for excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. The compound resists aggressive chemicals, petroleum oils and fuels, and aromatic hydrocarbons. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where amines or hot water and steam are present. The profile itself contributes two sealing bands per contact face rather than one and resistance to the spiral twisting that defeats round-section rings.

You will find this material specified across automotive fuel systems, chemical processing, and oil and gas.

QV70382 ships individually. Unit weight is approximately 47.39 g and nominal inside diameter is listed as 13 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
