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.

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.
  • Pressure Washers • Robotics • Steering Cylinders • Valves • Vapor Recovery Systems • Many more.


  • Aerospace • Automotive • Chemical Processing • Appliances • Machine Tools • Marine
