What it is

The O-RING is a Firebird sealing component for the blast tube on Firebird oil burners. It is fitted within the burner assembly to seal the blast tube joint and prevent oil seepage and air leakage at that connection. The part is listed by Firebird under part number FE65327520.

Signs this part needs replacing

  • Visible oil weeping or staining around the blast tube joint
  • The O-ring is hardened, flattened or cracked when inspected
  • The ring has perished or lost its elasticity and no longer seals under compression
  • Combustion readings drift or become difficult to set with the burner in service
  • Signs of air being drawn in at the blast tube connection

Before you order

  • Confirm the burner model matches one of the FB 4 R LN Low Nox variants listed above
  • Check the existing O-ring for size and condition before removal so the correct seal is refitted
  • Inspect the blast tube and its seating surfaces for damage or debris that could affect the seal
  • Verify the Firebird part number FE65327520 against the appliance documentation
