Non-axial restraint pipe coupling

STRAUB-FLEX-4

All pipe materials can be reliably connected with STRAUB-FLEX couplings. STRAUB-FLEX pipe couplings enable pipe connections for practically all conceivable pipe diameters, for the same or different types of pipe materials, various media and temperatures as well as for a wide range of the operating pressure values. The sealing sleeve separates the coupling casing from the pipe surface so that sound, vibrations and oscillations are optimally damped.

Remarks:
- Follow fitting instructions
- PN = working pressure considering the application loads
- Test pressure = PN x 1.5 (for example industry, water supply etc.)
- Burst pressure = approx. PN x 2
- Strip inserts included
- Additional sealing sleeves, pressure and temperature ranges on request

* These products are only available on request

STRAUB pipe couplings are made of the same or different materials depending on the diameter and size. The following overview shows the details. If you have any questions, please contact our application technology department.
