Hydraulic flange seals are manufactured from high-grade polyurethane and work extremely well for aggressive, heavy-duty and high pressure applications. Flange seals provide better resistance than O-rings to extrusion and compression within a working pressure of approx.350 bar and temperature of -35 to 90 degrees centigrade.

　　Unlike common O-rings, the seals are specifically designed to fit SAE standard location groove on the underside of a flange. The seal’s rectangular cross section fits accurately within the flange machined housing. The seals are available in six standard sizes to fit flanges from ½ to 2 in. These flange seals are developed especially for SAE flanges
