What it is
This is an Ariston O-ring with an internal diameter of 17.76mm and a cross-section of 1.78mm, supplied under part number 61308092. It is a sealing component used within the hydraulic and gas-carrying assemblies of Ariston gas boilers, where it seats between mating faces to prevent leakage. The O-ring forms a compression seal when the joint is assembled and tightened to the manufacturer's specification.
Signs this part needs replacing
- Visible water or gas weeping at the joint the O-ring seals
- The O-ring is hardened, brittle or has cracked with age and heat cycling
- The ring has flattened and no longer stands proud of its groove
- Persistent pressure loss or repeated low-pressure faults traced to a joint
- Discolouration or swelling of the rubber after contact with system water or inhibitor
Before you order
- Confirm the existing O-ring measures 17.76mm internal diameter with a 1.78mm cross-section
- Check your boiler model against the fitment list above before ordering
- Inspect the groove and mating faces for corrosion or scoring, as these will prevent a reliable seal
- Confirm how many O-rings the joint requires, as some assemblies use more than one
