568-038 FKM 75 SQUARE CUT RINGS

Ordered as SV70038, this is an AS568-038 black Viton® (FKM) 70 Shore A Square-Cut Ring measuring an inside diameter of 2.614 in (66.4 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.754 in (69.95 mm). The square-cut ring presents a flat rectangular section that cannot roll or twist in its groove, making it a dependable static seal.

As a material, Viton® (FKM) is valued 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, many acids, and engine and transmission fluids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). The profile itself contributes a flat contact band that spreads sealing load across a wider area and a rectangular section that will not roll in the groove. Note that a square section is less suited to high-speed rotary service, where the larger contact area raises friction and heat.

It sees regular use in high-temperature process equipment, semiconductor equipment, and chemical processing.

SV70038 ships individually. Nominal inside diameter is listed as 2 5/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
