Q-376 FLUOROELASTOMER 75 Q RING

Part number QV70376 is an AS568-376 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 9.725 in (247.02 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.145 in (257.68 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

This material stands up to engine and transmission fluids, petroleum oils and fuels, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for long service life in hot, chemically aggressive environments and outstanding high-temperature capability. 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 amines. The profile itself contributes lower compressive load required to achieve a seal and resistance to the spiral twisting that defeats round-section rings.

Typical settings include chemical processing, semiconductor equipment, and automotive fuel systems.

Stocked as QV70376 and sold individually. Nominal inside diameter is listed as 9 3/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
