What it is

The Baxi 643368 orifice plate is a flow restrictor disc listed by the manufacturer under part number 643368. It sits within the gas circuit of the appliance it is specified for, where the calibrated bore establishes a fixed restriction to gas flow. It is catalogued as a miscellaneous component rather than a model-specific spare.

Before you order

  • Confirm that 643368 matches the part number quoted in the appliance's installation, service or parts documentation.
  • Check the appliance model and Gas Council number so the correct orifice is selected.
  • Orifice plates are matched to a specific gas type and appliance input, so verify the required bore before ordering.
