What it is
This is a small sealing O-ring measuring 3.68mm x 1.78mm, used within the boiler's hydraulic or gas circuit. It is a genuine Alpha part, number 1.2268.
Signs this part needs replacing
- Water or condensate weeping from the joint the O-ring seals
- The O-ring is visibly perished, flattened or cracked
- A drop in system pressure traced back to the sealed joint
Before you order
- Match the O-ring's internal diameter and cross-section against the one removed
- Isolate the boiler and drain down the relevant circuit before replacing a sealing O-ring
- Lightly lubricate the new O-ring before fitting to avoid damaging it on assembly
