Q-118 FLUOROELASTOMER 75 Q RING

APG stocks the QV70118, an AS568-118 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 0.862 in (21.89 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.068 in (27.13 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 outstanding high-temperature capability. The compound resists engine and transmission fluids, petroleum oils and fuels, and chlorinated solvents. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Applications involving low-molecular-weight organic acids or hot water and steam call for a different compound. The profile itself contributes resistance to the spiral twisting that defeats round-section rings 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.

QV70118 ships individually. Unit weight is approximately 0.8183 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
