What it is

The Glow-worm 0020097321 is a nipple — a small threaded connector used within the pipework and hydraulic assemblies of Glow-worm gas boilers. It forms part of the internal connections on the Ultracom 2 range, joining components so that the water or gas path remains sealed under operating pressure. It is listed by the manufacturer as a serviceable spare for the appliances below.

Signs this part needs replacing

  • Visible weeping or a damp trace around the threaded joint when the boiler is running
  • Corrosion, pitting or discolouration on the nipple body or its threads
  • Water staining, scale or crusting on the surrounding casing or components
  • A joint that will not seal after correct tightening, indicating damaged threads
  • Loss of system pressure with no other obvious source of leakage

Before you order

  • Confirm the boiler model against the fit list above, as the Ultracom 2 range covers several outputs
  • Check the GC number on the appliance data badge to verify the exact variant
  • Inspect the existing nipple and its mating threads before removal so any additional damaged parts can be identified
  • Isolate the appliance and drain down as required before starting work
