Q-171 FLUOROELASTOMER 75 Q RING

QV70171 is an AS568-171 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 7.987 in (202.87 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 8.193 in (208.1 mm). In service, this quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

As a material, Viton® (FKM) is specified for excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. This material stands up to engine and transmission fluids, many acids, and petroleum oils and fuels. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or hot water and steam will shorten service life. The profile itself contributes two sealing bands per contact face rather than one and resistance to the spiral twisting that defeats round-section rings.

Typical settings include semiconductor equipment, high-temperature process equipment, and oil and gas.

QV70171 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
