What it is

The Vaillant 980308 is a packing ring, supplied as a pack of 10. It is a sealing component used on Vaillant VUI 362-7 and Aquaplus VUI 362-7 gas boilers, where it seals a joint against water or gas escape. The ring is a service item, so it is normally renewed whenever the joint it sits in is disturbed.

Signs this part needs replacing

  • Weeping or visible water at the joint the ring seals
  • Damp staining or corrosion around the sealing face
  • The ring is hardened, flattened or has lost its elasticity
  • Cracking, splitting or perishing visible on the ring
  • A leak reappears shortly after the joint has been reassembled

Before you order

  • Confirm your appliance model and GC number against the fitment list above
  • Check how many sealing points you are working on, as the pack contains 10 rings
  • Inspect the sealing faces for scoring or corrosion before fitting a new ring
  • Have the correct sealing compound or lubricant to hand if the manufacturer's procedure calls for it
