568-276 FKM 75 SQUARE CUT RINGS

Part number SV70276 is an AS568-276 black Viton® (FKM) 70 Shore A square profile Quad-Ring supplied with an inside diameter of 10.984 in (278.99 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 11.262 in (286.05 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

It resists many acids, aggressive chemicals, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is valued for very low compression set at elevated temperature, excellent resistance to compression set and permeation. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or hot water and steam are present.

You will find this material specified across high-temperature process equipment, aerospace, and semiconductor equipment.

SV70276 ships individually. Nominal inside diameter is listed as 11 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
