Q-223 FLUOROELASTOMER 75 Q RING

This quad-ring is supplied in AS568-223 black Viton® (FKM) 75 Shore A built to an inside diameter of 1.609 in (40.87 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.887 in (47.93 mm), catalogued under part number QV70223. It resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Viton® (FKM) is specified here for outstanding high-temperature capability and long service life in hot, chemically aggressive environments. This material stands up to petroleum oils and fuels, many acids, and chlorinated solvents. Published continuous service range is -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 lower compressive load required to achieve a seal.

Common environments for this compound include high-temperature process equipment, aerospace, and automotive fuel systems.

Stocked as QV70223 and sold individually. Unit weight is approximately 2.518 g and nominal inside diameter is listed as 1 5/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
