What it is

The Glow-worm pipe flange seal (part number 0020020757) is a sealing component for the pipe flange joint on Glow-worm gas boilers. It seals the flange connection to keep the joint watertight under normal operating pressure and temperature.

Signs this part needs replacing

  • Water weeping or dripping from the pipe flange joint
  • Visible cracking, flattening or hardening of the seal
  • Staining or mineral deposits around the flange
  • Repeated pressure loss on the heating circuit
  • Corrosion or pitting on the flange faces

Before you order

  • Confirm your boiler model and GC number against the fitment list
  • Check that part number 0020020757 matches the seal being replaced
  • Inspect the flange faces for damage before fitting the new seal
