STRAUB-FLEX-1
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 (Industry) = working pressure considering the application loads
- Test pressure = PN (Industry) x 1.5 (for example industry, water supply etc.)
- Burst pressure = approx. PN (Industry) x 2
- PN (Shipbuilding) = nominal pressure, includes four times safety factor (e.g. shipbuilding) Strip inserts are optional accessories
- Additional sealing sleeves, pressure and temperature ranges on request
- FPM / FKM only available as STRAUB-OPEN-FLEX
