What it is
The Ferroli O-Ring Sight Glass is the sealing ring that sits at the sight glass window on Ferroli Arena boilers. It seals the glass against the combustion chamber face, preventing flue gases and condensate from escaping past the window. This part supersedes the earlier code 810164.
Signs this part needs replacing
- Water or condensate weeping around the sight glass window
- Staining or corrosion tracking down from the sight glass area
- The O-ring feels hard, flattened or cracked when handled
- The seal has been disturbed during sight glass or burner work and no longer sits proud
- Persistent dampness at the window after the boiler has run
Before you order
- Confirm the boiler model against the fit list above, as Arena variants differ
- Check whether the O-ring alone is required or whether the sight glass itself is also damaged
- Inspect the old part for the superseded code 810164 to confirm you are matching the right item
- Examine the glass and its seating face for cracks or pitting before refitting
