PTFE Seals & Rings

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.

Advantages

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

Applications

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
Braking Systems
Combination Heat & Power Systems
