Grip couplings

WA-grip-couplings - Restraint Pipe connections - Couping for different size pipes.





WA-Grip couplings provide connections for differential diameter pipes or different pipe types.

Sealing gaskets in combination with the grippers, provide a watertight pull-out resistant connection.

The restraint couplings allow angular deflection up to 8 degrees (when flange adapters are used up to 4 degrees). Suitable for a working pressure up to 16 bars (232 psi) for water - 5 bars (72 psi) for gas pipelines.

Note : for use on PE and PVC pipes use pipe strengthening inserts.


  • Ductile cast iron
  • Gasket : EPDM or NBR
  • Bolts and washers : stainless steel (A2) 304L stainless
  • Nuts : stainless steel A4 316L stainless
  • Coating : Resicoat epoxy, blue
