Q-380 FLUOROELASTOMER 75 Q RING

The QV70380 is an AS568-380 black Viton® (FKM) 75 Shore A Quad-Ring built to an inside diameter of 11.475 in (291.47 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 11.895 in (302.13 mm). This quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

It resists aggressive chemicals, many acids, and chlorinated solvents. Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It should not be specified for service in low-molecular-weight organic acids or ketones and esters. 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 high-temperature process equipment, aerospace, and chemical processing.

Order part number QV70380, sold individually. Nominal inside diameter is listed as 11 1/2 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.
