What it is

This is a flange gasket supplied under the name GASKET by Firebird, and is listed as a flange gasket for G3B, G5 and G10 applications. It fits between mating flange faces on the boiler assembly to create a fluid-tight seal at the joint. The gasket is a service item on Firebird oil-fired boilers and is replaced whenever the joint is broken or begins to weep.

Signs this part needs replacing

  • Weeping or a visible oil film around the flange joint
  • Oil staining or a damp patch on the casing, floor or boiler base beneath the joint
  • A persistent kerosene smell near the boiler with no other obvious source
  • Gasket material that has hardened, cracked, flattened or partially disintegrated after the joint has been opened
  • Evidence of a previous seal breaking down when the flange is dismantled for other work

Before you order

  • Confirm the boiler model and output against the fitment list above
  • Check whether the boiler is a Kitchen, Popular Boilerhouse, Enviromax Heatpac, Enviromax Kitchen or Enviromax Systempac variant, as the fitment list covers several families
  • Verify the existing gasket and flange arrangement before removal so the correct item is matched
  • Have the Firebird code ZE3005787 to hand when ordering
