The SES TV Series from T-Lon provides universal application in severe operating conditions. The U-Cup seal design is made from PTFE and other polymer alloys and is mechanically energized with a corrosion resistant, V-shape cantilever beam spring. The spring maintains a constant live compression load and is further energized by system pressure. The TV series is available in standard and custom Rod, Piston and Face seal designs to meet your specific application requirements.
