Product Description


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:

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
