VITON X RING -368 SIZE

This quad-ring is supplied in AS568-368 black Viton® (FKM) 75 Shore A with an inside diameter of 7.725 in (196.22 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 8.145 in (206.88 mm), catalogued under part number QV70368. It seats in a standard o-ring gland while offering improved dynamic performance.

Viton® (FKM) is specified here for outstanding high-temperature capability and very low compression set at elevated temperature. The material holds up against engine and transmission fluids, petroleum oils and fuels, and aggressive chemicals. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or ketones and esters will shorten service life. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and two sealing bands per contact face rather than one.

Typical settings include aerospace, semiconductor equipment, and automotive fuel systems.

Stocked as QV70368 and sold individually. Unit weight is approximately 28.633 g and nominal inside diameter is listed as 7 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need?
