Q-457 FLUOROELASTOMER 75 Q RING

Ordered as QV70457, this is an AS568-457 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 13.975 in (354.97 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 14.525 in (368.94 mm). The quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Viton® (FKM) is specified here for outstanding high-temperature capability and very low compression set at elevated temperature. It resists many acids, petroleum oils and fuels, and engine and transmission fluids. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with hot water and steam or low-molecular-weight organic acids. 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 aerospace, semiconductor equipment, and chemical processing.

This item is sold individually under part number QV70457. Nominal inside diameter is listed as 14 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
