What it is

This is a Vaillant plug, part number 0010029435, supplied as a pack of five. It is a small sealing component used to blank off unused ports and tappings on Vaillant Ecotec and Ecotec PLUS gas boilers. It forms part of the appliance's water and gas circuit sealing arrangement.

Signs this part needs replacing

  • Visible weeping or a damp trace around a blanked port or tapping
  • Corrosion or scale build-up on the plug face or thread
  • The plug has been disturbed during servicing and no longer seals
  • Water staining or crusting on adjacent pipework or casing
  • A plug that has been cross-threaded or over-tightened and will not seat

Before you order

  • Confirm your appliance model against the fit list above
  • Check how many plugs are required for the job, as they are supplied in a pack of five
  • Verify the position and size of the port to be blanked against the manufacturer's parts list for your appliance
  • Inspect the sealing face of the port before fitting, as a damaged seat will not seal with a new plug
