The Goodman B2589343 Natural Gas Burner Orifice is a genuine OEM brass spud for the GDS81155CNA gas furnace and compatible Goodman/Amana equipment. This precision-drilled orifice threads into the manifold and meters the exact volume of natural gas delivered to each burner. The drilled bore size directly controls the furnace's BTU input and air-fuel ratio, so using the factory-spec orifice is essential for safe, efficient, correctly-sized flames.

Specifications

Material: Machined brass
Fuel type: Natural gas
Function: Burner gas metering orifice / spud
Thread: Factory manifold thread (per model spec)
Fits: Goodman GDS81155CNA and compatible natural-gas furnaces

OEM vs. Generic

The genuine OEM Goodman orifice is drilled to the precise bore diameter certified for this furnace's rated input. An incorrect bore — too large or too small — causes over-firing, sooting, delayed ignition, or a lazy yellow flame. Because gas metering is safety-critical, we recommend only the exact OEM part and never drilling out a substitute.

Installation Difficulty: Moderate

Rated Moderate (3/5). Shut off gas and power, remove the burner assembly or manifold as needed, unthread the old orifice with the correct wrench, and thread in the new spud. A gas-tightness leak check with soap solution is mandatory after installation. If you are not comfortable working on gas connections, hire a licensed HVAC technician.
