Q-464 FLUOROELASTOMER 75 Q RING

Ordered as QV70464, this is an AS568-464 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 17.455 in (443.36 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 18.005 in (457.33 mm). The quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Expect good resistance to many acids, aromatic hydrocarbons, and aggressive chemicals. Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

Typical settings include oil and gas, chemical processing, and semiconductor equipment.

Stocked as QV70464 and sold individually. Nominal inside diameter is listed as 17 1/2 inch. Review your operating media and conditions against this specification before installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
