Welflex PTFE expansion joints

Why Welflex PTFE expansion joints? Welflex PTFE expansion joints are very flexible, allowing a relatively large movement on a short installation length to be compensated. PTFE expansion joints have excellent chemical resistance.

Application

PTFE expansion joints

The pressure resistance of PTFE expansion joints decreases significantly at high temperatures. We recommend preferably using a standard version from our Welflex catalog. In addition to this range, we can also supply versions with higher pressure resistance.


  • Range: DN 25 to DN 900
  • Media: liquid and gas
  • Pressure stage: up to PN 16
  • Temperature: up to 200°C
  • Excellent chemical resistance
  • Flexible
  • Lower pressure resistance
  • Recording of vibration when pumping
  • Reducing noise at pumps and equipment
  • Recording of pipeline releases
  • Stress-free disconnection of critical equipment
