What it is

The Morco MCB2101 is a flue venturi nut manufactured by Morco Products. It secures the venturi assembly within the flue arrangement on compatible Morco FEB appliances. The venturi meters the air and flue gas path, so the nut needs to hold the assembly firmly in position.

Signs this part needs replacing

  • The nut is seized, rounded or will not tighten or release with normal tooling
  • Threads are corroded, cross-threaded or stripped, preventing a secure hold on the venturi
  • The venturi assembly is loose in the flue following a service or inspection
  • Visible corrosion or heat damage on the nut or its seating face

Before you order

  • Confirm the appliance model matches one of the FEB models listed above
  • Check the existing venturi fixing arrangement to ensure this nut is the correct fastener for the assembly
  • Inspect the venturi and its seating for damage before refitting, as a worn seat can prevent a secure joint
  • Have the appliance isolated and any required flue checks planned before starting work
