568-313 FKM 75 SQUARE CUT RINGS

SV70313 is an AS568-313 black Viton® (FKM) 70 Shore A Square-Cut Ring with an inside diameter of 0.662 in (16.81 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.082 in (27.48 mm). In service, this square-cut ring presents a flat rectangular section that cannot roll or twist in its groove, making it a dependable static seal.

As a material, Viton® (FKM) delivers outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Expect good resistance to many acids, aggressive chemicals, and petroleum oils and fuels. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with amines or hot water and steam. The profile itself contributes a flat contact band that spreads sealing load across a wider area and simple lathe-cut manufacture at low tooling cost. 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, oil and gas, and semiconductor equipment.
