The orifice threads into the manifold and precisely meters natural gas into each in-shot burner, setting the furnace's BTU input. A damaged, corroded, or incorrectly sized orifice throws off the fuel\/air ratio and can cause sooting, delayed ignition, lifting flame, or under-firing. Always match the drill size stamped on the spud to your gas type and altitude.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Threaded brass burner orifice \/ spud\u003c\/li\u003e\n\u003cli\u003eDrill Size: #43\u003c\/li\u003e\n\u003cli\u003eGas Type: Natural gas (verify rating plate for LP conversion)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GDT070-3B and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B4089343\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\u003eOrifice bore diameter directly controls gas flow and BTU output. The OEM B4089343 is precision-drilled and thread-matched to the GDT070-3B manifold. Generic spuds may have oversized or off-center bores that alter firing rate and combustion safety. For a fuel-metering component, OEM is the safe choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5).\u003c\/strong\u003e Shut off gas, remove the burner, unthread the old orifice with a nut driver, and hand-thread the replacement without over-tightening.
