The Goodman B4089343 is a genuine OEM #43 drill-size natural gas burner orifice (spud) for the ADS81155CXA gas furnace and compatible Goodman/Amana models. Threaded into the gas manifold, this precision brass orifice meters the exact fuel flow into each in-shot burner, setting the furnace's input rate and ensuring a properly sized, efficient flame.

Specifications

Orifice drill size: #43
Fuel: Natural gas
Material: Machined brass
OEM part number: B4089343
Equipment: Goodman / Amana gas furnaces

OEM vs. Generic

OEM orifices are drilled to the precise diameter Goodman specifies for the furnace's rated BTU input and gas pressure. Even a slightly off generic bore can over- or under-fire the unit, hurting efficiency and combustion safety. Always match the exact drill size and fuel type — OEM guarantees it.

Installation Difficulty

Moderate — back out the old spud and thread in the new one, then verify manifold pressure and flame. Shut off gas first and leak-check after. Use the correct fuel-specific size; for LP conversions, a different orifice is required. Professional service recommended.
