The orifice threads into the gas manifold and meters the precise volume of gas delivered to each in-shot burner. The correct orifice size is critical to firing rate, flame color, and safe, efficient combustion — never substitute an incorrect drill size or LP\/NG type.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B4089343\u003c\/li\u003e\n\u003cli\u003eOrifice Drill Size: #43\u003c\/li\u003e\n\u003cli\u003eGas Type: Natural gas (verify against your rating plate)\u003c\/li\u003e\n\u003cli\u003eType: Threaded brass burner orifice \/ spud\u003c\/li\u003e\n\u003cli\u003eFits: Goodman DDS81155CXA and select Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eSold individually — order one per burner\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine Goodman orifices are precision-drilled and gauged to the furnace's rated BTU input.
