Part number VQ4431 is an AS568-431 black Viton® (FKM) 75 Shore A quad profile Quad-Ring built to an inside diameter of 5.225 in (132.72 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.775 in (146.69 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.
As a material, Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. It resists petroleum oils and fuels, many acids, and chlorinated solvents. 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 ketones and esters.
You will find this material specified across automotive fuel systems, chemical processing, and high-temperature process equipment.
Reference part number VQ4431 when ordering; the item is sold individually. Nominal inside diameter is listed as 5 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
