What it is

A sealing ring supplied by Vaillant under part number 981373, sold as a pack of 10. It is a packing ring used to seal joints on the VUI 362-7 and Aquaplus VUI 362-7 appliance families. The ring forms the sealing face at the joint it is fitted to, preventing water or gas escape depending on the application.

Signs this part needs replacing

  • Visible weeping or damp staining at the joint the ring seals
  • The ring is flattened, hardened or cracked when inspected
  • Scale, corrosion or debris build-up on the sealing face
  • A leak that returns shortly after the joint is re-tightened
  • Water tracking down nearby components from the joint

Before you order

  • Confirm your appliance model against the fit list above
  • Check the data badge on the appliance to verify the model and variant
  • Assess how many joints require a new ring before ordering, as the pack contains 10
  • Inspect the sealing face for damage that would prevent a new ring from seating correctly
