What it is
This is an O-ring manufactured by Ariston, measuring 11.91mm by 2.62mm. It is a sealing component used within Ariston gas boiler assemblies to prevent water or gas leakage at a joint or connection. It is listed under the manufacturer's part number 65114940.
Signs this part needs replacing
- Visible water weeping or a damp trace around the joint the O-ring seals
- The O-ring is flattened, hardened or cracked when inspected
- Persistent pressure loss on the appliance with no other obvious cause
- A gas smell or detected leak at a sealed joint during a service check
- The O-ring has been disturbed during a repair and will not reseat cleanly
Before you order
- Confirm the part number 65114940 matches the item you are replacing
- Check the O-ring dimensions against the one removed, as similar sizes are not interchangeable
- Verify your appliance model against the fitment list above before ordering
- Inspect the mating surfaces for damage or debris, as this can cause a new O-ring to fail
