The orifice meters the exact volume of natural gas delivered to each burner, ensuring a clean, efficient flame and proper input rating. A clogged, corroded, or incorrectly sized orifice causes poor combustion, yellow flames, sooting, or lockouts — making this a critical maintenance and repair component.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOrifice size: #43\u003c\/li\u003e\n\u003cli\u003eMaterial: machined brass\u003c\/li\u003e\n\u003cli\u003eApplication: gas furnace main burner\u003c\/li\u003e\n\u003cli\u003eFits: Goodman ADS80703ANA and compatible models\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B4089343\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B4089343\u003c\/strong\u003e guarantees the exact drill size and thread pitch for correct gas input and safe combustion.
