VITON QUAD RING -175 SIZE

Part number QV70175 is an AS568-175 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 8.987 in (228.27 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 9.193 in (233.5 mm). A quad-ring provides a dual sealing band on each contact face for improved reliability.

Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. The compound resists aggressive chemicals, petroleum oils and fuels, and many acids. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Applications involving low-molecular-weight organic acids or amines call for a different compound. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and lower compressive load required to achieve a seal.

Maintenance and OEM teams specify it across semiconductor equipment, automotive fuel systems, and high-temperature process equipment.

Reference part number QV70175 when ordering; the item is sold individually. Unit weight is approximately 7.896 g and nominal inside diameter is listed as 9 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.
