What it is

The electrode packing is a sealing component used on Navien LCB 700 series boilers. It seals around the electrode where it passes through the appliance casing, preventing leakage and maintaining correct combustion chamber sealing. It is supplied by Navien under part number 20043443B.

Signs this part needs replacing

  • Visible cracking, hardening or perishing of the packing material
  • Water or condensate weeping around the electrode entry point
  • Soot staining or discolouration at the electrode seal
  • The packing no longer seats correctly when the electrode is refitted
  • Sealing faults identified during a combustion analysis or service inspection

Before you order

  • Confirm the appliance is a Navien LCB 700 series boiler
  • Check the model, output and internal or external variant against the fit list
  • Inspect the electrode and its seal during the service before ordering
  • Verify the part number 20043443B against the manufacturer's parts list for your appliance
