A new series of hydraulic flange seals, manufactured from high-grade polyurethane, are for aggressive and heavy-duty applications. The material provides added resistance to extrusion and compression set over –40 to 230°F and a pressure rating of up to 6,000 psi.
Unlike common O-rings, the seals are specifically designed to fit SAE standard location groove on the underside of a flange. The seals custom-manufactured rectangular cross section is formed and sized to accurately locate within the flange machined housing. The seals are available in six standard sizes to fit flanges from ½ to 2 in.
