Q-352 FLUOROELASTOMER 75 Q RING

Part number QV70352 is an AS568-352 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 4.85 in (123.19 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.27 in (133.86 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Viton® (FKM) is specified here for outstanding high-temperature capability and very low compression set at elevated temperature. It resists many acids, aromatic hydrocarbons, and petroleum oils and fuels. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). The profile itself contributes lower compressive load required to achieve a seal and two sealing bands per contact face rather than one.

You will find this material specified across chemical processing, automotive fuel systems, and aerospace.

QV70352 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
