PIRTEK has introduced a new series of flange seals. These new seals are manufactured from a high grade of polyurethane, which was developed for aggressive and heavy-duty applications. The material provides added resistance to extrusion and compression set over a temperature range of -40°F to +230°F and a pressure rating of up to 6,000 psi. These new seals are specifically designed to fit the SAE standard location groove on the underside of the flange. The seals are available in six standard sizes to suit flanges from 1/2 to 2 in.
