Q-326 FLUOROELASTOMER 75 Q RING

Part number QV70326 is an AS568-326 black Viton® (FKM) 75 Shore A Quad-Ring built to an inside diameter of 1.6 in (40.64 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.02 in (51.31 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

As a material, Viton® (FKM) is valued for excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. The material holds up against chlorinated solvents, aromatic hydrocarbons, and many acids. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). The profile itself contributes resistance to the spiral twisting that defeats round-section rings and a parting line located away from the sealing surface.

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

This item is sold individually under part number QV70326. Unit weight is approximately 5.9676 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
