Q-167 FLUOROELASTOMER 75 Q RING

QV70167 is an AS568-167 black Viton® (FKM) 75 Shore A Quad-Ring built to an inside diameter of 6.987 in (177.47 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.193 in (182.7 mm). In service, this quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

It resists chlorinated solvents, many acids, and petroleum oils and fuels. Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

You will find this material specified across chemical processing, oil and gas, and semiconductor equipment.
