568-363 FKM 75 SQUARE CUT RINGS

SV70363 is an AS568-363 black Viton® (FKM) 70 Shore A square profile Quad-Ring with an inside diameter of 6.475 in (164.47 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.895 in (175.13 mm). In service, this quad-ring provides a dual sealing band on each contact face for improved reliability.

It resists many acids, chlorinated solvents, and petroleum oils and fuels. Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or ketones and esters are present.

Common environments for this compound include semiconductor equipment, aerospace, and high-temperature process equipment.

Order part number SV70363, sold individually. Nominal inside diameter is listed as 6 1/2 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.
