Welflex PTFE expansion joints
Information
Why Welflex PTFE expansion joints? Welflex PTFE expansion joints are highly flexible, which means that a relatively large movement can be compensated at a short overall length. PTFE expansion joints offer excellent chemical resistance.
The pressure resistance of PTFE expansion joints decreases sharply at high temperatures. We recommend using a standard version from our Welflex catalogue. In addition to this range, we can also supply versions offering higher pressure resistance.

- Reducing noise nuisance from pumps and devices
- Absorption of pipe expansions
- Stress-free disconnection of critical equipment
Versions
The motion absorption capacity increases with a larger number of waves. However, pressure resistance decreases with a larger number of waves. The 3-wave version offers the most optimal ratio between motion absorption and pressure resistance and is therefore used most often.
