Goodman B4089343 #43 Burner Orifice

The Goodman B4089343 is a genuine OEM natural gas burner orifice (drill size #43) for the DHS80453AXA gas furnace. The orifice — also called a spud — meters the exact gas flow into each in-shot burner, setting the furnace's rated BTU input. Using the correct orifice size is essential for safe combustion, proper flame color, and rated efficiency.

Specifications

  • Drill/orifice size: #43
  • Fuel: Natural gas
  • Thread: OEM Goodman burner rail fit
  • Material: Machined brass
  • Fits: Goodman DHS80453AXA and compatible models
  • OEM part number: B4089343

OEM vs. Generic

Genuine OEM orifices are precision-drilled and deburred to Goodman's exact specification, guaranteeing the correct BTU input and clean flame. Generic drilled orifices can vary by thousandths of an inch, over- or under-firing the furnace and producing sooting or CO. Always match the OEM size for the equipment and gas type.

Installation Difficulty

Easy. The orifice threads into the burner manifold and is swapped with a nut driver after the gas is shut off. Verify orifice size stamped on the part matches your furnace rating plate before firing.

Never enlarge or re-drill an orifice. Confirm gas type and manifold pressure after installation.
