The orifice meters the precise volume of gas delivered to each in-shot burner, setting the furnace's input rate and flame quality. A worn, enlarged, or debris-clogged orifice causes lazy yellow flames, sooting, or under\/over-firing — replacing it restores factory-rated combustion.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill size:\u003c\/strong\u003e #43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Threaded brass burner orifice \/ spud\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel:\u003c\/strong\u003e Natural gas (verify against furnace rating plate)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Machined brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GMNT115-5B and compatible GMNT series\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Orifice drill size directly determines BTU input and is safety-critical. This OEM Goodman spud is drilled to the exact #43 spec the furnace was certified for. Generic or mis-sized orifices risk over-firing, incomplete combustion, and carbon monoxide production, so genuine sizing is strongly recommended.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty:\u003c\/strong\u003e Easy (1 of 5). The orifice threads into the manifold and requires only a properly sized socket or wrench. Shut off gas and power, confirm the #43 size matches your fuel type and altitude, and leak-check the manifold with soap solution after installation.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058131419507,"sku":"GOODMAN-11741","price":5.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-43-burner-orifice-for-gmnt115-5b-b4089343","provider":"National HVAC Parts","version":"1.0","type":"link"}
