Q-337 FLUOROELASTOMER 75 Q RING

Ordered as QV70337, this is an AS568-337 black Viton® (FKM) 75 Shore A quad profile Quad-Ring supplied with an inside diameter of 2.975 in (75.57 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.395 in (86.23 mm). The quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Expect good resistance to engine and transmission fluids, chlorinated solvents, and aggressive chemicals. Viton® (FKM) is specified for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

Maintenance and OEM teams specify it across aerospace, chemical processing, and oil and gas.

QV70337 ships individually. Unit weight is approximately 11.787 g. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
