Q-021 FLUOROELASTOMER 75 Q RING

Part number QV70021 is an AS568-021 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 0.926 in (23.52 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.066 in (27.08 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

As a material, Viton® (FKM) is known for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. This material stands up to many acids, aggressive chemicals, and engine and transmission fluids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). The profile itself contributes two sealing bands per contact face rather than one and a parting line located away from the sealing surface.

It sees regular use in chemical processing, high-temperature process equipment, and oil and gas.
