Drilled to a #43 gauge, it meters the exact gas flow each burner needs to hold the manufacturer-rated BTU input and a clean, stable flame. Worn, plugged, or mismatched orifices cause lazy yellow flames, delayed ignition, and sooting, so replacing a failed spud restores safe, efficient combustion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: B4089343\u003c\/li\u003e\n\u003cli\u003eOrifice size: #43 drill\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas\u003c\/li\u003e\n\u003cli\u003eMaterial: Machined brass\u003c\/li\u003e\n\u003cli\u003eThread: Standard Goodman burner spud thread\u003c\/li\u003e\n\u003cli\u003eFits: GMP125-5 and compatible Goodman gas furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a factory OEM Goodman orifice, drilled and gauged to spec so the burner input matches the rating plate exactly.
