T-Seal High-Pressure Bi-Directional Piston Seal
High-pressure compact piston seal design. The design utilizes two positively actuated live anti-extrusion back-up rings to support very high pressure from both sides. Available in Viton®, Nitrile, H-Nbr, Aflas® and other materials to retrofit standard O-ring grooves designed for no back-up, single, or two back-up rings. Retro fits seals of similar design.
