Q-131 FLUOROELASTOMER 75 Q RING

QV70131 is an AS568-131 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 1.674 in (42.52 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.88 in (47.75 mm). In service, this quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. The compound resists 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). Exposure to amines or ketones and esters will shorten service life. The profile itself contributes lower compressive load required to achieve a seal and two sealing bands per contact face rather than one.

Common environments for this compound include aerospace, high-temperature process equipment, and oil and gas.

Stocked as QV70131 and sold individually. Unit weight is approximately 1.5125 g. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
