568-330 FKM 75 SQUARE CUT RINGS

Part number SV70330 is an AS568-330 black Viton® (FKM) 70 Shore A square profile Quad-Ring measuring an inside diameter of 2.1 in (53.34 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.52 in (64.01 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Viton® (FKM) is specified here for very low compression set at elevated temperature and outstanding high-temperature capability. The material holds up against petroleum oils and fuels, aggressive chemicals, and chlorinated solvents. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Applications involving ketones and esters or amines call for a different compound.

Maintenance and OEM teams specify it across semiconductor equipment, high-temperature process equipment, and oil and gas.

SV70330 ships individually. Nominal inside diameter is listed as 2 1/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
