568-104 FKM 75 SQUARE CUT RINGS

Part number SV70104 is an AS568-104 black Viton® (FKM) 70 Shore A square profile Quad-Ring measuring an inside diameter of 0.112 in (2.84 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.318 in (8.08 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

As a material, Viton® (FKM) is widely chosen for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. The material holds up against chlorinated solvents, aggressive chemicals, and many acids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where amines or low-molecular-weight organic acids are present.

It sees regular use in aerospace, automotive fuel systems, and oil and gas.
