Q-164 FLUOROELASTOMER 75 Q RING

APG stocks the QV70164, an AS568-164 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 6.237 in (158.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 6.443 in (163.65 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Viton® (FKM) is specified here for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. It resists engine and transmission fluids, chlorinated solvents, and aggressive chemicals. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Applications involving amines or hot water and steam call for a different compound. The profile itself contributes lower compressive load required to achieve a seal and two sealing bands per contact face rather than one.

Common environments for this compound include oil and gas, chemical processing, and automotive fuel systems.

Stocked as QV70164 and sold individually. Nominal inside diameter is listed as 6 1/4 inch. Review your operating media and conditions against this specification before installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
