What it is

The Ideal 173380 is a flow flange used on 4-9 section heat exchangers in Ideal Commercial appliances. It forms the connection point where the flow pipework meets the heat exchanger body, sealing the joint and directing water out of the exchanger on its way around the system. It is a direct replacement component for the original factory-fitted flange.

Signs this part needs replacing

  • Water weeping or tracking from the flange joint where it meets the heat exchanger
  • Visible corrosion, pitting or scale build-up on the flange face
  • Staining or mineral deposits around the flange indicating a long-standing slow leak
  • Repeated loss of system pressure with no other obvious source
  • Distortion of the flange face preventing a reliable seal against the exchanger

Before you order

  • Confirm the appliance model and, where shown on the data badge, the GC number against the compatibility list below
  • Check the heat exchanger section count on the appliance matches the 4-9 section range of this flange
  • Compare the numbers on the old component with 173380, 1179415 and 85535513 before fitting
  • Inspect the mating gasket or seal and renew it if it shows any sign of hardening or damage
