This precision-drilled brass burner spud meters the exact flow of natural gas into the burner venturi, setting the furnace's rated BTU input. A worn, corroded, or incorrectly sized orifice causes sooting, lazy flames, delayed ignition, or under-firing.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B2589343\u003c\/li\u003e\n\u003cli\u003eType: Burner Orifice \/ Spud\u003c\/li\u003e\n\u003cli\u003eFuel: Natural Gas\u003c\/li\u003e\n\u003cli\u003eMaterial: Machined Brass\u003c\/li\u003e\n\u003cli\u003eCompatible Model: Goodman GMN120-5\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine Goodman OEM orifice\u003c\/strong\u003e is drilled to the precise diameter specified for your furnace's input rating and altitude, guaranteeing a clean, correctly proportioned flame. Generic orifices with approximate bore sizes risk over- or under-firing, incomplete combustion, and dangerous CO production. With a gas-metering component, exact OEM sizing is a safety matter — not a preference.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Requires shutting off the gas supply and using a wrench to back the orifice out of the manifold. Thread the new spud carefully to avoid cross-threading brass, then leak-test every joint with soap solution before relighting. If you are not confident working with gas connections, hire a licensed HVAC technician. Allow 20–30 minutes.\u003c\/p\u003e\u003cp\u003eBacked by our fit guarantee. Questions?
