Sterling HVAC 11J36R04694-028 Standard Orifice Nat Gas #42

The Sterling HVAC 11J36R04694-028 Standard Orifice Nat Gas #42 regulates gas flow by controlling the amount of fuel delivered to the burner assembly during operation. The orifice allows natural gas to pass through a specific opening size to support the required combustion process. Gas heating equipment in HVAC systems uses this component to maintain controlled fuel distribution within the burner section. The orifice is fitted into the gas pathway where accurate flow delivery is required. Its flow control operation creates the proper fuel conditions needed for the heating sequence.
