What it is
This is a pump packing supplied by Navien under part number 20044484A. It forms part of the circulating pump assembly on Navien LCB 700 boilers, sealing the pump against leakage at the shaft. It is used across both combi and system variants of the LCB 700 range.
Signs this part needs replacing

- A visible trickle or damp patch beneath the pump during operation
- Corrosion or scale build-up around the pump seal face
- System pressure dropping repeatedly with no other visible leak
