Q-461 FLUOROELASTOMER 75 Q RING

The QV70461 is an AS568-461 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 15.955 in (405.26 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 16.505 in (419.23 mm). This quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

The compound resists many acids, engine and transmission fluids, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is known for outstanding high-temperature capability and long service life in hot, chemically aggressive environments. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where amines or ketones and esters are present. The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.

You will find this material specified across semiconductor equipment, oil and gas, and aerospace.

Order part number QV70461, sold individually. Nominal inside diameter is listed as 16 inch. 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.
