The Baxi 5115769 O-Ring 60 mm is a genuine replacement sealing component designed to create a secure, flexible seal at key connections within your boiler or heating system. O-rings provide a resilient barrier against leaks in water or gas joints, helping maintain correct system pressure, preventing drips and protecting internal components from moisture ingress. A worn, brittle or distorted O-ring can lead to leaks, pressure loss or boiler fault codes, so fitting the correct OEM sealing ring is essential for dependable operation.

This 60 mm O-ring is compatible with Baxi boilers and systems that specify part number 5115769 in their technical documentation. To ensure accurate fitment and optimal sealing performance, always verify the part number on your existing O-ring or consult your boiler’s service information before installation, as sealing components vary by application and model.

Supplied ready for direct replacement, the 5115769 O-Ring fits into the designated groove or connection when installed by a qualified engineer. Choosing this genuine Baxi component helps restore proper sealing integrity, supports stable pressures and contributes to reliable heating and hot-water performance in compatible boilers and systems.
