The Goodman B4089343 Burner Orifice is a genuine OEM #43 drill-size brass gas spud for the Goodman GMPE075-3A furnace. 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.

Specifications

OEM Part Number: B4089343
Orifice Size: #43 drill
Fuel: Natural gas (verify against your rating plate)
Material: Machined brass with standard burner thread
Fits: Goodman GMPE075-3A and compatible Goodman/Amana gas burners

OEM vs. Generic

This genuine OEM orifice 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. For a combustion component, use the factory part to keep the furnace burning safely at its rated BTU.

Installation Difficulty

Moderate (3/5). Requires removing the manifold/burner assembly and correctly threading and torquing the orifice — over-tightening cracks the spud. Shut off gas and power, and always leak-check with soap solution after reassembly. Combustion work is best performed by a licensed HVAC technician.
