Source1 2920423042 42 Gas Orifice Replacement S1-02920423042

Product Description

The Source1 2920423042 is an OEM replacement gas orifice designed for York HVAC equipment. This part carries the alternate part number S1-02920423042 and is used in gas-fired furnaces and heating systems that require precise fuel metering. A gas orifice is a small but critical component in any gas heating system. It controls the flow of natural gas or propane into the burner assembly. The correct orifice size ensures the right air-to-fuel ratio, which directly affects combustion efficiency, flame appearance, and overall heating performance. Using the wrong orifice can lead to incomplete combustion, sooting, overheating, or unsafe operation. The 2920423042 is an OEM-specified part, meaning it meets the exact tolerances and material standards set by York for their original equipment. HVAC technicians and service professionals rely on OEM orifices to restore furnace performance to factory specifications. This is especially important during a gas valve replacement, burner conversion, or routine maintenance on York gas furnaces. Gas orifices are typically sized by a drill number that corresponds to a specific orifice diameter. The size 42 designation on this part refers to the orifice drill size, which determines how much gas flows through at a given inlet pressure. Proper orifice sizing is essential for both safety and efficiency in any gas appliance. Sourcing the correct OEM part eliminates guesswork and ensures compatibility with the original equipment design. This replacement part is suited for HVAC service contractors, facilities maintenance teams, and technicians who work on York branded heating systems and need a reliable, specification-matched component to complete a repair or service call.
