Q-347 FLUOROELASTOMER 75 Q RING

Ordered as QV70347, this is an AS568-347 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 4.225 in (107.32 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.645 in (117.98 mm). The quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

The material holds up against many acids, aggressive chemicals, and petroleum oils and fuels. Viton® (FKM) is valued for long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or hot water and steam will shorten service life. The profile itself contributes two sealing bands per contact face rather than one and a parting line located away from the sealing surface.

It sees regular use in semiconductor equipment, high-temperature process equipment, and automotive fuel systems.

This item is sold individually under part number QV70347. Unit weight is approximately 16.537 g and nominal inside diameter is listed as 4 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
