NORMACONNECT® COMBI GRIP/COMBI GRIP E pipe axial restraint couplings are used to connect plastic pipes with metal pipes. The coupling features a special anchoring ring with rows of flat teeth, which are pressed into the pipe surface without damaging the material when used on plastic pipes. At the same time the force applied is distributed evenly across the pipe surface.

The coupling also features on the other side an anchoring ring with conically stamped teeth which grip into the pipe surface when used with metal pipes. Due to the special design of the anchoring ring the coupling can withstand high vibration loads, pressures and angular deflection.

NORMA Connect

When joining plastic pipes made from soft materials (i.e PE or PP) a support sleeve must be used. The support sleeve has to be inserted into the pipe end within the area to be joined and thus protects the pipe from being deformed.

To be used with NORMACONNECT® PLAST GRIP/PLAST GRIP E, COMBI GRIP/COMBI GRIP E in W5 (1.4571) material. For copper and CuNiFe pipes an optional support sleeve made from brass is available on request.
