NORMA GRIP strong pipe couplings for metal and cast iron pipes

Home→ Catalog→ Additional Equipment→ Couplings NORMA→ Grip

NORMA GRIP E and NORMA GRIP INOX strong pipe coupling are designed to connect metal and cast iron pipes with high internal pressure and axial restraint. This type of couplings is considered the most reliable for connecting pipelines, since they combine the properties of the Rapid connectors and Kralle couplings. The use of pipe couplings of the GRIP/GRIP E series for fixing metal and plastic pipes prevents their axial deflection and longitudinal stretching.

Advantages of GRIP/GRIP E coupling:

  • no need deburring;
  • coupling ready for installation;
  • lock can be rotated and positioned in the most convenient way;
  • no need to ensure the coaxiality of the pipes (saving time and money).

The anchoring ring with conically stamped teeth provides reliable and durable fixation. Also due to the teeth the GRIP coupling can withstand high vibration loads.

They are able to absorb unforeseen deformations and are suited for installation in seismically active zones.

GRIP E couplings are an economical option for GRIP couplings - they have hollow locking bolts.

Made of high quality steels.
