568-323 FKM 75 SQUARE CUT RINGS

Part number SV70323 is an AS568-323 black Viton® (FKM) 70 Shore A square profile Quad-Ring supplied with an inside diameter of 1.287 in (32.69 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.707 in (43.36 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Expect good resistance to petroleum oils and fuels, aromatic hydrocarbons, and chlorinated solvents. Viton® (FKM) delivers very low compression set at elevated temperature, excellent resistance to compression set and permeation. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving low-molecular-weight organic acids or ketones and esters call for a different compound.

It sees regular use in chemical processing, high-temperature process equipment, and aerospace.

SV70323 ships individually. Nominal inside diameter is listed as 1 5/16 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
