Q-463 FLUOROELASTOMER 75 Q RING

QV70463 is an AS568-463 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 16.955 in (430.66 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 17.505 in (444.63 mm). In service, this quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. The compound resists aggressive chemicals, aromatic hydrocarbons, and engine and transmission fluids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where hot water and steam or low-molecular-weight organic acids are present. The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

It sees regular use in chemical processing, oil and gas, and semiconductor equipment.

Reference part number QV70463 when ordering; the item is sold individually. Nominal inside diameter is listed as 17 inch. Check the compound against your process media, pressure and temperature before committing to a design.
