The orifice (or spud) threads into the manifold and precisely meters gas flow into each burner. The #43 drill size sets the BTU input for the burner — using the correct orifice is essential for proper flame, efficiency, and safe combustion. A worn, enlarged, or incorrectly sized orifice can cause lazy yellow flames, sooting, or improper firing rate.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Threaded burner orifice \/ spud\u003c\/li\u003e\n\u003cli\u003eOrifice size: #43 drill\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas (verify size for your fuel\/altitude)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman ADS80703AXA furnace\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B4089343\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis genuine Goodman orifice is drilled and threaded to factory spec, guaranteeing the correct gas flow rate and a leak-free seal at the manifold.
