What it is

A pack of three nuts supplied by Vaillant under part number 0020213157. The nuts are used on a range of Vaillant domestic gas appliances, including HOME, Ecofit and Ecotec models, where they secure threaded connections within the appliance. They are a small consumable component, typically required when a joint is disturbed during servicing or repair.

Signs this part needs replacing

  • Visible corrosion or surface pitting on the nut
  • Rounded or damaged hex flats that will not take a spanner cleanly
  • Weeping or damp staining at the joint the nut secures
  • The nut has been removed and the joint is being remade
  • Thread damage or cross-threading preventing the nut from tightening correctly

Before you order

  • Confirm your appliance model against the fitment list above
  • Check the manufacturer's parts list for your specific model and serial number
  • Establish how many nuts are required for the joint being worked on
  • Isolate the appliance and depressurise the relevant circuit before dismantling
