568-013 FKM 75 SQUARE CUT RINGS

Ordered as SV70013, this is an AS568-013 black Viton® (FKM) 70 Shore A Square-Cut Ring built to an inside diameter of 0.426 in (10.82 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.566 in (14.38 mm). The square-cut ring seals with a broad flat contact band instead of the line contact of a round-section ring.

Viton® (FKM) is specified here for very low compression set at elevated temperature and outstanding high-temperature capability. The compound resists chlorinated solvents, many acids, and petroleum oils and fuels. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to ketones and esters or hot water and steam will shorten service life. The profile itself contributes a rectangular section that will not roll in the groove 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.

Maintenance and OEM teams specify it across semiconductor equipment, oil and gas, and automotive fuel systems.
