Each orifice is precision-drilled to a \u003cstrong\u003e#43 drill size\u003c\/strong\u003e, metering the exact gas flow needed to deliver rated BTU input and a clean, stable flame. A worn, corroded, or incorrectly sized orifice causes yellow flames, sooting, poor combustion, and lockouts — replacing it restores efficient, safe heating.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B4089343\u003c\/li\u003e\n\u003cli\u003eDrill Size: #43\u003c\/li\u003e\n\u003cli\u003eFuel: Natural Gas\u003c\/li\u003e\n\u003cli\u003eMaterial: Machined brass\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMPE100-4 and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eThread: Standard Goodman burner manifold\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a factory-original Goodman orifice, drilled and gauged to OEM tolerances so BTU input matches the furnace rating plate exactly. Aftermarket orifices often vary in bore diameter, which can push firing rate out of spec and trip safety limits.
