Threaded into the gas manifold, this precision-machined brass orifice meters the exact gas flow into each in-shot burner. Correct orifice sizing is essential for proper BTU input, clean combustion, and safe operation — an incorrect or worn orifice can cause under-firing, sooting, or overheating.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: B4089343\u003c\/li\u003e\n\u003cli\u003eType: Burner orifice \/ spud\u003c\/li\u003e\n\u003cli\u003eDrill size: #43 (approx. 0.089\")\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas\u003c\/li\u003e\n\u003cli\u003eMaterial: Machined brass\u003c\/li\u003e\n\u003cli\u003eFits: Goodman DHS80905CXA and related furnace platforms\u003c\/li\u003e\n\u003cli\u003eSold: Each (one per burner)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eOEM Goodman orifices\u003c\/strong\u003e are drilled to Goodman's exact specification for the furnace's rated input and altitude assumptions. \u003cstrong\u003eGeneric orifices\u003c\/strong\u003e can vary by a thousandth or two, throwing off the gas rate and combustion.
