The orifice meters the precise gas flow into each burner, setting the flame size and the furnace's rated input. Using the correct #43 orifice is essential for a clean blue flame, proper firing rate, and safe, efficient combustion. A worn, plugged, or wrong-size orifice causes poor flames, sooting, delayed ignition, or over\/under-firing.\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\u003eFuel: Natural gas (verify against your rating plate)\u003c\/li\u003e\n\u003cli\u003eMaterial: Machined brass with standard burner thread\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMPE075-3A and compatible Goodman\/Amana gas burners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine OEM orifice\u003c\/strong\u003e is machined to the exact #43 bore and thread pitch specified for your furnace's input rating. Off-brand spuds can vary in bore diameter, which shifts the firing rate outside spec.
