Q-120 FLUOROELASTOMER 75 Q RING

APG stocks the QV70120, an AS568-120 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 0.987 in (25.07 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.193 in (30.3 mm). A quad-ring provides a dual sealing band on each contact face for improved reliability.

Viton® (FKM) offers long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. This material stands up to aromatic hydrocarbons, aggressive chemicals, and engine and transmission fluids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

You will find this material specified across high-temperature process equipment, automotive fuel systems, and semiconductor equipment.

Stocked as QV70120 and sold individually. Unit weight is approximately 0.9418 g and nominal inside diameter is listed as 1 inch.
