568-211 FKM 75 SQUARE CUT RINGS

This square-cut ring is supplied in AS568-211 black Viton® (FKM) 70 Shore A supplied with an inside diameter of 0.796 in (20.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.074 in (27.28 mm), catalogued under part number SV70211. It presents a flat rectangular section that cannot roll or twist in its groove, making it a dependable static seal.

Viton® (FKM) is valued for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Expect good resistance to aromatic hydrocarbons, chlorinated solvents, and aggressive chemicals. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). The profile itself contributes simple lathe-cut manufacture at low tooling cost and a flat contact band that spreads sealing load across a wider area. Note that a square section is less suited to high-speed rotary service, where the larger contact area raises friction and heat.

Typical settings include semiconductor equipment, oil and gas, and automotive fuel systems.

This item is sold individually under part number SV70211. Unit weight is approximately 1.373 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
