The Baxi 237259 Blue Flue Seal is a genuine replacement sealing ring designed for use in the flue system of compatible Baxi boilers. This high-quality seal ensures an airtight connection between flue components, preventing flue gas leakage and maintaining safe, efficient boiler operation.

Over time, flue seals can become worn, brittle, or damaged due to heat and system movement. A compromised seal can lead to combustion issues, flue gas escape, noise, or boiler lockouts. Replacing it with this genuine Baxi part restores proper sealing and system integrity.
