The orifice meters the precise volume of gas delivered to each burner, ensuring a clean, efficient flame, correct BTU input, and safe combustion. A clogged, corroded, or incorrectly sized orifice causes soot, delayed ignition, and poor heating performance — replacing with the exact OEM part restores factory operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOrifice size: #43 drill\u003c\/li\u003e\n\u003cli\u003eFuel type: Natural gas\u003c\/li\u003e\n\u003cli\u003eMaterial: Machined brass\u003c\/li\u003e\n\u003cli\u003eThread: OEM standard burner spud thread\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMPE075-3 gas furnace\u003c\/li\u003e\n\u003cli\u003eOEM part number: B4089343\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine OEM orifices are machined and gauged to Goodman's exact drill-size tolerance, which directly governs gas input and flame quality.
