Part number QV70276 is an AS568-276 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 10.984 in (278.99 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 11.262 in (286.05 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.
As a material, Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. It resists many acids, petroleum oils and fuels, and chlorinated solvents. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or amines will shorten service life. The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.
Maintenance and OEM teams specify it across automotive fuel systems, chemical processing, and high-temperature process equipment.
Reference part number QV70276 when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
