568-471 FKM 75 SQUARE CUT RINGS

Part number SV70471 is an AS568-471 black Viton® (FKM) 70 Shore A Square-Cut Ring measuring an inside diameter of 21.955 in (557.66 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 22.505 in (571.63 mm). A square-cut ring presents a flat rectangular section that cannot roll or twist in its groove, making it a dependable static seal.

Viton® (FKM) is specified here for excellent resistance to compression set and permeation, outstanding high-temperature capability. The material holds up against many acids, chlorinated solvents, and engine and transmission fluids. The material carries a published service range of -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.

Typical settings include chemical processing, high-temperature process equipment, and aerospace.
