Vari-gib couplings

Vari-Gib non-restrained mechanical couplings provide an effective method for connecting pipes with equal or unequal diameters.

Vari-Gib Non-restrained Mechanical Couplings


  • Vari-Gib Couplings can be installed without the need to disassemble, significantly improving speed and ease of installation
  • The variable OD range of each coupling often enables application on more than one pipe type and size, thereby significantly reducing stockholding requirements
  • Compatible with most pipe types
  • Specially designed wedge shaped nitrile rubber gaskets are suitable for use with water, wastewater and gas mediums
  • Fasteners have a captive head configuration to enable single spanner operation, facilitating ease of field assembly
  • Fasteners are 316 stainless steel for long life operation. Galvanised mild steel is available in sizes up to DN 300
  • A three bolt design is used in sizes up to DN 150 for ease of installation
  • Components are pre-lubricated during assembly to assist installation
  • An extended range of stepped couplings are now available
  • Manufacturing facility certified to the ISO 9001 quality assured standard
