Brief description

* Normal strength:
  watertight to 2.5 bar, DIBt approval Z - 42.5 - 442, up to DN 600

* Extra strength:
  * watertight to 2.5 bar, DIBt approval Z - 42.5 - 442, up to DN 600

KERA.Mat Metal banded flexible couplings (M-seals) are used to connect 2 pipe spigots in nominal sizes DN 100 to DN 500. M-seals can be ordered in 2 versions: type 2A (normal type) and type 2B (wider version)

M-seals with compensation elements (bushes) in the sizes 4, 8, 12, 16, 24 and 32 mm for joining two pipe spigots with different external diameters from 160 to 1399 mm.

Re-System

Our stainless steel coupling (normal/extra strength) and our flexible couplings type 2B in diameters DN 100 to DN 600 are supplied with the patented pipe joint identification system (RE-system). The system enables joints made with our flexible couplings to be marked on the inside to prevent misinterpretations in future sewer inspections.

Furthermore, customers can be sure that the flexible coupling they ordered has actually been installed. During assembly of the flexible coupling, the coupling “clip” is placed at the pipe crown between the pipe ends to be connected.

PRODUCT ADVANTAGES

  • Unambiguous classification of the joint 
  • Prevention of unnecessary rehabilitation costs resulting from misinterpretations in future sewer inspections 
  • Quality assurance: the type of flexible coupling can be checked from the inside 
  • Easy to install 
  • No extra costs 
  • The ID is in the pipe crown, close to the pipe wall 
  • Resistant to high-pressure flushing

Tools & Services

COUPLING CALCULATOR

For connecting spigots, the Coupling Calculator works out the type of coupling and, if necessary, the quantity and type of compensating rings required.
