Q-222 FLUOROELASTOMER 75 Q RING

The QV70222 is an AS568-222 black Viton® (FKM) 75 Shore A quad profile Quad-Ring measuring an inside diameter of 1.484 in (37.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.762 in (44.75 mm). This quad-ring provides a dual sealing band on each contact face for improved reliability.

Expect good resistance to many acids, aromatic hydrocarbons, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for outstanding high-temperature capability and long service life in hot, chemically aggressive environments. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving low-molecular-weight organic acids or amines call for a different compound.

It sees regular use in semiconductor equipment, automotive fuel systems, and aerospace.

Reference part number QV70222 when ordering; the item is sold individually. Unit weight is approximately 2.5897 g. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
