What it is

The CONNECTOR SET (UK) is a Worcester Bosch pipework connection component, supplied under part number 8737604670. It is intended for use on Worcester Greenstar 2000 Combi and Greenstar Gr2301IW Combi appliances, where it forms part of the boiler's pipework connection arrangement.

Signs this part needs replacing

  • Visible weeping or dripping at the pipework connection points
  • Corrosion, staining or scale build-up around the connector
  • Damp patches or water tracking beneath the appliance
  • A connection that is loose, disturbed or damaged during servicing
  • Evidence of an existing joint that will not seal correctly

Before you order

  • Confirm the appliance model and GC number against the Fits list above
  • Check the part number 8737604670 matches the component being removed
  • Verify whether the boiler is NG or LPG, as fitment entries cover both
  • Inspect the surrounding pipework for damage that may also need attention
