What it is
This is a pack of four heat exchanger plate seals, part number 720884901, made by Baxi. It is classed as a gasket, O-ring, seal and washer and is used to seal the plates within the plate heat exchanger of Baxi combi boilers, keeping the heating and domestic hot water circuits separated and preventing leaks.
Before you order
- Check the boiler model and serial number, particularly the serial number ending for the 124 and 128 ErP Combi models, as these are listed by serial suffix.
- Confirm the gas type for GA models (LPG or NG), as the fit list separates these variants.
- Compare the boiler's gas council (GC) number against the appliance data plate before ordering.
