Q-358 FLUOROELASTOMER 75 Q RING

QV70358 is an AS568-358 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 5.6 in (142.24 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.02 in (152.91 mm). In service, this quad-ring provides a dual sealing band on each contact face for improved reliability.

As a material, Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Expect good resistance to chlorinated solvents, petroleum oils and fuels, and many acids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with amines or low-molecular-weight organic acids. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and two sealing bands per contact face rather than one.

Common environments for this compound include semiconductor equipment, automotive fuel systems, and chemical processing.
