Nordyne 661023R Natural Gas Burner Orifice 0.023″ #23

The Nordyne 661023R Natural Gas Burner Orifice 0.023" #23 is a precision metering component that regulates the amount of natural gas delivered to a burner assembly. Its calibrated opening controls fuel flow into the combustion area, allowing the burner to receive the specified gas volume required for ignition and flame formation. Threaded into the burner manifold of gas-fired equipment, it is used with HVAC systems where proper fuel delivery is needed for combustion control. The unit provides consistent gas passage through the burner assembly, maintains proper fuel-to-air balance, and supports steady flame features within the heating unit.
