Baxi Duo Tec 28 HE Hydraulic Inlet Assembly 12L – Refurbished | Part No. 5132454

The hydraulic inlet assembly is the central water management unit in a Baxi Duo Tec, Platinum, or ERP combi boiler — housing the filling loop connection, pressure relief valve port, and internal flow group components including the diverter valve, bypass, and automatic air vent.
