What it is

The Vaillant plug (pack of 2), part number 0020143524, is a small sealing component used on Vaillant ecoTEC VU series gas boilers. It closes off a port or tapping on the appliance, retaining system pressure and preventing leakage at that point. The part is supplied by Vaillant in a pack of two.

Signs this part needs replacing

  • Weeping or damp staining around the plug position
  • Corrosion or scale build-up on the plug body
  • Rounded or damaged hex, making the plug difficult to remove or torque correctly
  • Plug missing or left out after previous service work
  • Signs of water tracking past the plug seating area

Before you order

  • Confirm your boiler model and GC number against the fitment list above
  • Check how many plugs are required for the job, as the part is supplied in a pack of two
  • Inspect the seating area for damage before fitting a replacement plug
