Q-146 FLUOROELASTOMER 75 Q RING

Ordered as QV70146, this is an AS568-146 black Viton® (FKM) 75 Shore A Quad-Ring built to an inside diameter of 2.612 in (66.34 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.818 in (71.58 mm). The quad-ring provides a dual sealing band on each contact face for improved reliability.

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 aggressive chemicals, petroleum oils and fuels, and engine and transmission fluids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving low-molecular-weight organic acids or ketones and esters call for a different compound. The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

Common environments for this compound include semiconductor equipment, chemical processing, and high-temperature process equipment.

QV70146 ships individually. Unit weight is approximately 2.3328 g and nominal inside diameter is listed as 2 5/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
