What it is

Vaillant tube, part number 0020046760, is a formed pipe component used in VU 656 series gas boilers. It is listed by Vaillant for the Ecomax 665 and Ecotec VU 656/4-5 models shown below. The tube forms part of the boiler's internal assembly and is replaced as a single item.

Signs this part needs replacing

  • Visible corrosion, pitting or surface scaling on the tube
  • Water weeping, staining or residue at the tube connections
  • Discolouration or heat damage suggesting localised overheating
  • Flow or pressure symptoms traced back to a restricted tube
  • A leak found on the tube during service or a pressure test

Before you order

  • Confirm your boiler model against the fit list above
  • Check the part number on the existing component or against the manufacturer's parts list
  • Check whether any seals, washers or fixings are needed separately, as these are not confirmed as included
