Adaptor couplings are designed to provide a solution to most requirements for adaptation between pipes of different sizes and materials up to DN300. The range covers both traditional and new pipe materials an important factor with the increased development of brownfield sites.

The couplings consist of a stepped moulded sleeve with different diameters at each end, which is sealed on the pipes by two clamping bands.


  • Connecting pipes of different outside diameters and/or materials without the use of a bush.
  • Connecting laterals to sewers or drains.
  • Connecting pipes to prefabricated structures e.g. manholes, inspection chambers, septic tanks.
