568-450 FKM 75 SQUARE CUT RINGS

Part number SV70450 is an AS568-450 black Viton® (FKM) 70 Shore A Square-Cut Ring built to an inside diameter of 10.475 in (266.07 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 11.025 in (280.04 mm). A square-cut ring seals with a broad flat contact band instead of the line contact of a round-section ring.

Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, outstanding high-temperature capability. It resists chlorinated solvents, many acids, and engine and transmission fluids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or amines are present. The profile itself contributes a rectangular section that will not roll in the groove 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.

Maintenance and OEM teams specify it across chemical processing, semiconductor equipment, and aerospace.

Stocked as SV70450 and sold individually. Nominal inside diameter is listed as 10 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
