The orifice threads into the manifold and precisely meters natural gas into each in-shot burner. The drill size — \u003cstrong\u003e#43\u003c\/strong\u003e — sets the BTU input per burner, so using the correct orifice is essential for safe, efficient, correctly-rated combustion.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e B4089343\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Main burner orifice \/ spud\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill size:\u003c\/strong\u003e #43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel:\u003c\/strong\u003e Natural gas\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Machined brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Meters gas flow into the burner to set BTU input\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman ADV80905CXBB and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Genuine Goodman orifices are drilled and gauged to the exact #43 specification and manifold thread. An incorrectly sized or off-brand orifice changes the fuel rate, which can over-fire the furnace (safety hazard, cracked heat exchanger) or under-fire it (poor heat, sooting). For gas-metering parts, always use OEM.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty:\u003c\/strong\u003e Moderate — must match manifold thread and gas type; typically replaced with the manifold accessible.
