568-466 FKM 75 SQUARE CUT RINGS

The SV70466 is an AS568-466 black Viton® (FKM) 70 Shore A square profile Quad-Ring supplied with an inside diameter of 18.455 in (468.76 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 19.005 in (482.73 mm). This quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

It resists aromatic hydrocarbons, engine and transmission fluids, and petroleum oils and fuels. Viton® (FKM) is known for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It is not the right choice where hot water and steam or low-molecular-weight organic acids are present.

Maintenance and OEM teams specify it across oil and gas, high-temperature process equipment, and automotive fuel systems.

Stocked as SV70466 and sold individually. Nominal inside diameter is listed as 18 1/2 inch. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
