PTFE Seal Material Offers Greater Durability, Longer Operating Life & Other Mission-Critical Benefits 

Polytetrafluoroethylene (PTFE) seals and piston rings have started to replace their carbon counterpart as PTFE seals and rings offer greater durability, have a longer operating life, and can be operated at various pressures, velocities and temperatures.

PTFE seals and rings are becoming more common in a variety of applications and industries because of the unique advantages they offer.


PTFE seals and rings have various properties that make it ideal for a wide range of applications. Some advantages of PTFE seals and rings include:

  • Low-Friction
  • High Wear Resistance
  • Chemical Resistance
  • Ease of Machinability
  • Broad Temperature Tolerance (-328F to +500F)
  • Anti-Adhesive Properties
  • Low Stick Slip


PTFE seals and rings are ideal for a variety of applications, particularly in fluid & gas applications.

Other applications where PTFE seals and rings are common include:

  • Gas Compressors (Air, Oxygen, Hydrogen, Carbon Dioxide, Ammoniac, etc.)
  • Hydraulic & Pneumatic Cylinders
  • Metallic & Thermoplastic Cylinders
  • Dosage Pumps
  • Liquid Pumps with High Fluidity
  • Liquid Oxygen Pumps
  • Liquidated Gas Compressors (butane, propane, etc.)
  • Liquid and Gas Vacuum Pumps
  • Reciprocating Compressors
  • Rocking Piston Pumps
