The orifice meters natural gas into each burner tube, and its #43 drill size sets the firing rate for the appliance. A worn, enlarged, or wrong-size orifice causes poor flame quality, sooting, or under-firing — installing the correct OEM #43 spud restores the factory input rating and a clean blue flame.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B4089343\u003c\/li\u003e\n\u003cli\u003eOrifice Size: #43 drill\u003c\/li\u003e\n\u003cli\u003eType: Brass burner orifice \/ gas spud\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman GMP125-4 gas furnace\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (Genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOrifice sizing is critical to safe combustion, so the genuine OEM B4089343 is precision-drilled to the exact #43 specification.
