Q-020 FLUOROELASTOMER 75 Q RING

The QV70020 is an AS568-020 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 0.864 in (21.95 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.004 in (25.5 mm). This quad-ring provides a dual sealing band on each contact face for improved reliability.

Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Expect good resistance to chlorinated solvents, petroleum oils and fuels, and aromatic hydrocarbons. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving hot water and steam or low-molecular-weight organic acids call for a different compound. The profile itself contributes lower compressive load required to achieve a seal and a parting line located away from the sealing surface.

Common environments for this compound include aerospace, automotive fuel systems, and oil and gas.

Reference part number QV70020 when ordering; the item is sold individually. Unit weight is approximately 0.364 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
