The orifice meters the precise volume of natural gas delivered to each burner, controlling the gas-to-air ratio that determines flame quality, combustion efficiency, and rated BTU output. A worn, corroded, or incorrectly sized orifice produces yellow or lifting flames, sooting, delayed ignition, or a loss of heating capacity — installing the correct OEM orifice restores clean, safe combustion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B2589343\u003c\/li\u003e\n\u003cli\u003eFuel Type: Natural Gas\u003c\/li\u003e\n\u003cli\u003eApplication: Furnace burner assembly\u003c\/li\u003e\n\u003cli\u003eCompatible Model: Goodman GDT045-3A\u003c\/li\u003e\n\u003cli\u003eMaterial: Machined brass\u003c\/li\u003e\n\u003cli\u003eType: Threaded metering orifice \/ spud\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a genuine OEM orifice with a factory-verified drill size, guaranteeing the exact gas flow your furnace's heat exchanger and gas valve were designed for. Generic or drilled-out orifices risk incorrect BTU input, which can cause overheating, poor efficiency, or unsafe combustion.
