Baxi Expansion Vessel Flexible Tube Spare Part De Dietrich 7769817

The Baxi expansion vessel flexible tube spare part is a hose that connects the expansion vessel to the boiler's water circuit. It allows for movement and vibration absorption while maintaining a secure connection. Made from reinforced rubber or metal braid, it withstands system pressure and temperature. Over time, flexible tubes can degrade and cause leaks, so replacement is necessary for reliable operation. Ensure the tube length and fittings match your Baxi model for a proper seal. This component helps maintain the correct water pressure and protects the expansion vessel from stress.
