Q-327 FLUOROELASTOMER 75 Q RING

QV70327 is an AS568-327 black Viton® (FKM) 75 Shore A quad profile Quad-Ring supplied with an inside diameter of 1.725 in (43.82 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.145 in (54.48 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, aromatic hydrocarbons, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in low-molecular-weight organic acids or amines.

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

Reference part number QV70327 when ordering; the item is sold individually. Unit weight is approximately 6.38 g and nominal inside diameter is listed as 1 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
