568-469 FKM 75 SQUARE CUT RINGS

Part number SV70469 is an AS568-469 black Viton® (FKM) 70 Shore A Square-Cut Ring with an inside diameter of 19.955 in (506.86 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 20.505 in (520.83 mm). A square-cut ring presents a flat rectangular section that cannot roll or twist in its groove, making it a dependable static seal.

Expect good resistance to aromatic hydrocarbons, engine and transmission fluids, and aggressive chemicals. Viton® (FKM) offers outstanding high-temperature capability and long service life in hot, chemically aggressive environments. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in amines or low-molecular-weight organic acids. The profile itself contributes a flat contact band that spreads sealing load across a wider area and greater resistance to extrusion than a round section of the same size. Note that a square section is less suited to high-speed rotary service, where the larger contact area raises friction and heat.

You will find this material specified across automotive fuel systems, chemical processing, and oil and gas.
