The PTU spring energized PTFE Seal rod & piston is not specifically designed for just one industry or application. The chemical and physical properties of its compounds make it a powerful problem solver in many situations. The seals always seem to gravitate toward certain difficult applications which include

  • Harsh chemicals and solvents.

  • High temperatures up to 260℃.

  • Cryogenic temperatures down to -40℃.

  • Unlubricated applications.

  • Where low friction is required.

  • High pressures up to 450bar.

  • High surface speeds when other seals overheat.

  • The most popular PTFE fillers used for PTU spring energized PTFE Seal rod & piston products are carbon fiber, fiberglass, aromatic polyester and graphite. Virgin PTFE is also popular for these products when conditions are mild.


  • • Compressors • Cryogenics • FDA Clean Grade • Jet Engines • Hydraulic Cylinders • Paint Sprayers.
