What it is
The packing for the heat exchanger in/out adaptor is a Navien sealing component used at the heat exchanger connection points on NCB-CE and NPE-AWE/SWE appliances. It seals the joint between the adaptor and the heat exchanger, preventing water loss at the inlet and outlet connections. The part is supplied under Navien part number 20006868A.
Signs this part needs replacing

- Damp staining, corrosion or limescale tracking around the adaptor joint
- A visible split, flattening or hardening of the existing packing
- System pressure loss that cannot be traced to another part of the circuit
- Water marks on components below the heat exchanger connection points
Before you order

- Check which adaptor connection is leaking, as the packing is used at the heat exchanger inlet and outlet
- Inspect the adaptor and mating face for damage or distortion before refitting
- Isolate and drain the appliance before removing the adaptor
