What it is
A pack of 4 plate heat exchanger seals for the Baxi Duo-Tec 2 and EcoBlue Advanced boiler range, matching genuine part number 720884901. The seals fit between the plates of the heat exchanger to prevent water and gas leaks at the joints. This is a compatible (non-genuine) equivalent of the Baxi part, not a manufacturer-branded item.
Signs this part needs replacing
- Water leaking from the plate heat exchanger casing or joints
- Boiler losing system pressure with no visible external leak
- Limescale or water staining around the heat exchanger
- Boiler locking out repeatedly on low pressure
Before you order
- Confirm your exact model against the boiler's rating plate — this seal kit covers several Duo-Tec/EcoBlue/Neta-Tec variants
- This is a compatible replacement, not a genuine Baxi part — check with our technical team first if a genuine part is required
- Isolate and drain the system before removing the heat exchanger
- Fitting must be carried out by a Gas Safe registered engineer
