What it is
The Ariston 65104320 is a sealing O-ring with listed dimensions of 21.89 mm x 2.62 mm. It is a small rubber sealing component used within Ariston gas boiler assemblies to prevent water or gas leakage at a jointed connection. It is supplied as a single O-ring.
Signs this part needs replacing
- Visible cracking, flattening or hardening of the O-ring
- Water weeping or a damp trace around the joint it seals
- A gas smell or detected leak at the sealed connection
- The O-ring has been disturbed during servicing and no longer sits correctly in its groove
- Discolouration or swelling of the rubber after contact with system water or inhibitor
Before you order
- Confirm the part number 65104320 matches the number shown in your appliance's parts list
- Check the O-ring dimensions against the one being removed, as more than one size is used across the range
- Identify your exact boiler model and, where applicable, the GC number before ordering
- Inspect the sealing face and groove for damage or debris before fitting a new O-ring
