Q-429 FLUOROELASTOMER 75 Q RING

Part number QV70429 is an AS568-429 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 4.975 in (126.37 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.525 in (140.34 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Viton® (FKM) offers long service life in hot, chemically aggressive environments and outstanding high-temperature capability. The compound resists many acids, aggressive chemicals, and petroleum oils and fuels. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). The profile itself contributes two sealing bands per contact face rather than one and lower compressive load required to achieve a seal.

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

This item is sold individually under part number QV70429. Unit weight is approximately 33.353 g and nominal inside diameter is listed as 5 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
