Q-322 FLUOROELASTOMER 75 Q RING

The QV70322 is an AS568-322 black Viton® (FKM) 75 Shore A Quad-Ring built to an inside diameter of 1.225 in (31.12 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.645 in (41.78 mm). This quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. It resists many acids, engine and transmission fluids, and aggressive chemicals. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving hot water and steam or ketones and esters call for a different compound. The profile itself contributes lower compressive load required to achieve a seal and a parting line located away from the sealing surface.

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

QV70322 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.
