The Baxi 247429 O-Ring (22 mm × 3 mm) is a genuine Baxi replacement sealing ring designed to create a secure, leak-resistant connection between components in compatible boiler systems. Made from durable, heat-resistant material, this O-ring helps maintain water tightness in joints where precision sealing is required, supporting safe and efficient operation of the heating and hot water circuits. It is intended to be fitted by a qualified heating engineer during servicing, maintenance, or when replacing worn or deteriorated seals.

Compatibility for the 247429 O-ring includes Baxi Combi, Duo-Tec, and Megaflo boiler models that use this specific 22 mm × 3 mm seal size. Always check the exact boiler model and parts specification before installation to ensure correct fit and performance.

Using a genuine Baxi O-ring helps prevent leaks, supports stable system pressure, and contributes to the long-term reliability and smooth operation of your central heating and hot water system.
