The orifice meters the exact volume of gas delivered to each burner, producing a clean, correctly shaped flame. A clogged, corroded, or wrong-size orifice causes lifting flames, sooting, poor ignition, and reduced heat output — replacing it restores safe, efficient combustion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B4089343\u003c\/li\u003e\n\u003cli\u003eComponent: Burner orifice \/ gas spud\u003c\/li\u003e\n\u003cli\u003eOrifice Size: #43 drill\u003c\/li\u003e\n\u003cli\u003eCompatible Model: Goodman GMP150-5\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOrifice sizing is critical to safe gas metering.
