What it is

The Ariston 65104304 is a sealing O-ring measuring 22.22mm by 2.62mm section. It is used across the Ariston CLAS and E-Combi boiler families to seal a joint between mating components and prevent water or gas leakage at that connection. The ring is a serviceable item and is replaced whenever the joint is broken or the seal has hardened.

Signs this part needs replacing

  • Visible water weeping or a damp trace around the joint the ring seals
  • The ring is flattened, hardened or cracked when the joint is opened
  • The ring has swollen or stretched and no longer sits squarely in its groove
  • A gas smell or a joint that fails a tightness test after reassembly
  • Recurring leaks at the same connection after the joint has been disturbed

Before you order

  • Confirm the part number 65104304 matches the one shown in your appliance's parts list
  • Check the O-ring dimensions against the groove it sits in, as similar sizes are not interchangeable
  • Inspect the mating faces for scoring or corrosion before fitting a new ring
  • Have the correct sealing procedure and any required jointing practice to hand for the connection being worked on
