Q-269 FLUOROELASTOMER 75 Q RING

QV70269 is an AS568-269 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 8.734 in (221.84 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.012 in (228.9 mm). In service, this quad-ring provides a dual sealing band on each contact face for improved reliability.

Viton® (FKM) delivers outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. This material stands up to petroleum oils and fuels, many acids, and engine and transmission fluids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where amines or hot water and steam are present. The profile itself contributes a parting line located away from the sealing surface and resistance to the spiral twisting that defeats round-section rings.

It sees regular use in high-temperature process equipment, automotive fuel systems, and chemical processing.
