What it is

A brass nipple with a G3/4 inch thread, manufactured by Glow-worm and supplied under part number 0020186172. It is a small threaded connector used within the hydraulic assemblies of Glow-worm domestic gas boilers. The part forms part of the boiler's internal pipework and connection arrangement.

Signs this part needs replacing

  • Weeping or dripping at the threaded joint
  • Thread damage or cross-threading preventing a sound seal
  • Scale build-up restricting flow through the nipple
  • Leaks reappearing after the joint has been re-made

Before you order
