This precision-drilled orifice threads into the manifold and meters the exact volume of natural gas delivered to each burner. The drilled bore size directly controls the furnace's BTU input and air-fuel ratio, so using the factory-spec orifice is essential for safe, efficient, correctly-sized flames.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMaterial: Machined brass\u003c\/li\u003e\n\u003cli\u003eFuel type: Natural gas\u003c\/li\u003e\n\u003cli\u003eFunction: Burner gas metering orifice \/ spud\u003c\/li\u003e\n\u003cli\u003eThread: Factory manifold thread (per model spec)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GDS81155CNA and compatible natural-gas furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e orifice is drilled to the precise bore diameter certified for this furnace's rated input.
