Goodman B4089343 #43 Burner Orifice

The Goodman B4089343 is a genuine OEM natural gas burner orifice (spud) with a #43 drill size, engineered for the DDS81155CXA gas furnace and compatible Goodman/Amana manifolds. The orifice threads into the gas manifold and meters the precise volume of gas delivered to each in-shot burner. The correct orifice size is critical to firing rate, flame color, and safe, efficient combustion — never substitute an incorrect drill size or LP/NG type.

Orifice Drill Size: #43

Type: Threaded brass burner orifice / spud
Fits: Goodman DDS81155CXA and select Goodman/Amana furnaces

OEM vs. Generic

Genuine Goodman orifices are precision-drilled and gauged to the furnace's rated BTU input. Even a slightly oversized generic orifice can overfire the furnace, cause sooting, or trip safety limits. Because the orifice controls the fuel-air ratio, OEM is the safe choice.

Installation Difficulty

Easy — About 10–20 minutes with a nut driver or socket. Shut off gas and power, remove the manifold, unthread the old orifice, and hand-thread the new spud (do not overtighten brass). Leak-check every joint with soap solution before returning to service.

Always confirm gas type and orifice size on the furnace rating plate. When in doubt, consult a licensed HVAC technician.
