Q-467 FLUOROELASTOMER 75 Q RING

APG stocks the QV70467, an AS568-467 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 18.955 in (481.46 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 19.505 in (495.43 mm). A quad-ring provides a dual sealing band on each contact face for improved reliability.

Viton® (FKM) is specified here for very low compression set at elevated temperature, excellent resistance to compression set and permeation. It resists many acids, engine and transmission fluids, and aggressive chemicals. 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 ketones and esters call for a different compound. The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.

It sees regular use in semiconductor equipment, high-temperature process equipment, and oil and gas.

Order part number QV70467, sold individually. Nominal inside diameter is listed as 19 inch. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
