568-023 FKM 75 SQUARE CUT RINGS

APG stocks the SV70023, an AS568-023 black Viton® (FKM) 70 Shore A square profile Quad-Ring supplied with an inside diameter of 1.051 in (26.7 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.191 in (30.25 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Expect good resistance to chlorinated solvents, engine and transmission fluids, and many acids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).

Maintenance and OEM teams specify it across chemical processing, high-temperature process equipment, and aerospace.
