Q-441 FLUOROELASTOMER 75 Q RING

QV70441 is an AS568-441 black Viton® (FKM) 75 Shore A quad profile Quad-Ring measuring an inside diameter of 6.975 in (177.17 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 7.525 in (191.14 mm). In service, this quad-ring provides a dual sealing band on each contact face for improved reliability.

Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. Expect good resistance to many acids, engine and transmission fluids, and chlorinated solvents. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to ketones and esters or hot water and steam will shorten service life.

Common environments for this compound include semiconductor equipment, oil and gas, and chemical processing.
