Q-160 FLUOROELASTOMER 75 Q RING

QV70160 is an AS568-160 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 5.237 in (133.02 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 5.443 in (138.25 mm). In service, this quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

This material stands up to petroleum oils and fuels, engine and transmission fluids, and many acids. That behavior comes from the compound itself: Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and two sealing bands per contact face rather than one.

Maintenance and OEM teams specify it across semiconductor equipment, high-temperature process equipment, and oil and gas.

QV70160 ships individually. Nominal inside diameter is listed as 5 1/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
