Q-112 FLUOROELASTOMER 75 Q RING

Ordered as QV70112, this is an AS568-112 black Viton® (FKM) 75 Shore A Quad-Ring built to an inside diameter of 0.487 in (12.37 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.693 in (17.6 mm). The quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. Expect good resistance to chlorinated solvents, aggressive chemicals, and petroleum oils and fuels. 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 lower compressive load required to achieve a seal and resistance to the spiral twisting that defeats round-section rings.

Maintenance and OEM teams specify it across semiconductor equipment, automotive fuel systems, and chemical processing.

Stocked as QV70112 and sold individually. Unit weight is approximately 0.5198 g. Check the compound against your process media, pressure and temperature before committing to a design.
