What it is

The Glow-worm 0020018548 is a gas pipe seal grommet for the Xtramax HE appliance family. It fits where the gas pipe enters the boiler casing and forms the seal around the pipe. It is a serviceable component, renewed when the existing seal is damaged, hardened or displaced.

Signs this part needs replacing

  • Visible cracking, splitting or perishing of the rubber
  • The grommet has hardened and no longer seals against the pipe
  • A gas smell or a detected leak at the pipe entry point
  • The grommet is loose, displaced or missing from the casing
  • Leak detection fluid bubbles at the pipe entry during a tightness test

Before you order

  • Confirm the appliance is a Glowworm Xtramax HE and check the GC number against the manufacturer's parts list.
  • Check that the part number 0020018548 matches the component being replaced or the manufacturer's diagram.
  • Any work on gas-carrying components must be carried out by a Gas Safe registered engineer.
