Q-275 FLUOROELASTOMER 75 Q RING

QV70275 is an AS568-275 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 10.484 in (266.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 10.762 in (273.35 mm). In service, this quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

This material stands up to aggressive chemicals, petroleum oils and fuels, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with hot water and steam or low-molecular-weight organic acids. The profile itself contributes two sealing bands per contact face rather than one and a parting line located away from the sealing surface.

Maintenance and OEM teams specify it across oil and gas, aerospace, and semiconductor equipment.

This item is sold individually under part number QV70275. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
