Q-450 FLUOROELASTOMER 75 Q RING

The QV70450 is an AS568-450 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 10.475 in (266.07 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 11.025 in (280.04 mm). This quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments and industry benchmark where nitrile reaches its thermal limit. The compound resists petroleum oils and fuels, aromatic hydrocarbons, and aggressive chemicals. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or amines. The profile itself contributes two sealing bands per contact face rather than one and a parting line located away from the sealing surface.

You will find this material specified across semiconductor equipment, high-temperature process equipment, and aerospace.

Order part number QV70450, sold individually. Unit weight is approximately 65.215 g and nominal inside diameter is listed as 10 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
