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 Braking Systems Combination Heat & Power Systems As an industry leading hydraulic seal and piston ring manufacturer, our PTFE seals and rings are available in a wide range of piston ring and sealing ring configurations, including:
