What it is

The Navien flexible hose for the expansion vessel is a connection component used on Navien NCB-CE series gas boilers. It links the expansion vessel to the boiler's hydraulic circuit so the vessel can absorb pressure changes in the heating system. It is supplied as a single part under reference 20032195A.

Signs this part needs replacing

  • Weeping, damp patches or crusting at the hose connection to the expansion vessel
  • System pressure that repeatedly drops after topping up
  • Hardening, cracking or perishing of the hose material
  • Water staining or corrosion around the vessel connection or adjacent casing
  • Pressure gauge fluctuation traced to a leaking vessel connection

Before you order

  • Confirm the boiler model and serial number against the fitment list
  • Inspect the hose connection at the expansion vessel to confirm the fault before ordering
  • Check the part reference 20032195A against the existing hose or the manufacturer's parts list
