568-126 FKM 75 SQUARE CUT RINGS

The SV70126 is an AS568-126 black Viton® (FKM) 70 Shore A square profile Quad-Ring with an inside diameter of 1.362 in (34.59 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.568 in (39.83 mm). This quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Viton® (FKM) is specified here for outstanding high-temperature capability and industry benchmark where nitrile reaches its thermal limit. The material holds up against petroleum oils and fuels, chlorinated solvents, and aromatic hydrocarbons. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Applications involving low-molecular-weight organic acids or hot water and steam call for a different compound.

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

This item is sold individually under part number SV70126. Nominal inside diameter is listed as 1 3/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
