What it is

This is a Vaillant sealing ring, supplied as a pack of 10 under part number 193535 (also written 19-3535). It is a small elastomeric seal that sits between two mating faces inside a Vaillant heating appliance, closing the gap between them so that water cannot escape past the joint. Sealing rings of this type are fitted at unions, connections and component interfaces where a compression joint alone would not hold water.

Signs this part needs replacing

  • Water weeping or dripping from the joint the ring seals
  • The ring has hardened, flattened or cracked with age and no longer springs back when compressed
  • Scale, corrosion or mineral deposits are visible around the seal face
  • Water staining or residue on the casing or components below the joint
  • A leak that returns shortly after the joint is re-tightened

Before you order

  • Confirm part number 193535 against your appliance's parts list or exploded diagram
  • Check the appliance serial and GC number to identify the exact model variant
  • Inspect the mating faces for scoring, pitting or corrosion before fitting a replacement ring, as a damaged face will not seal
  • Note that the rings are supplied in packs of 10, so order the quantity you need for the job
