O-ring 14 x 3 Baxi De Dietrich 7769880

This O-ring, sized 14 x 3 mm, is a small but crucial sealing component for Baxi boilers. It is used in various connections, such as between the heat exchanger and pipework or at pump unions, to prevent water leaks. Made from high-quality rubber, it provides a tight, durable seal that withstands heat and pressure. If you are servicing your Baxi boiler and notice any weeping or dripping, replacing the old O-rings with this genuine part can quickly resolve the issue and restore system integrity.
