The Goodman B2589343 Natural Gas Orifice is a genuine OEM burner orifice (spud) precision-drilled for the Goodman GMP050-3 gas furnace running on natural gas. The orifice threads into the manifold and meters the exact volume of gas fed to each burner, setting the furnace's firing rate and flame characteristics. Because orifice sizing is calibrated to fuel type and BTU output, using the correct factory-drilled spud is essential for safe, efficient, code-compliant operation.

Specifications

Part type: Natural gas burner orifice (spud)
Compatible model: Goodman GMP050-3 gas furnace
OEM part number: B2589343
Fuel type: Natural gas (factory-drilled bore)
Fitment: direct-fit factory replacement, threads into burner manifold

OEM vs. Generic

The genuine Goodman orifice guarantees the exact drill size and thread specification the GMP050-3 requires, ensuring proper gas metering and flame quality. An incorrectly sized generic orifice can over- or under-fire the burner, producing soot, carbon monoxide, or nuisance lockouts. With a combustion-critical part, OEM is non-negotiable.

Installation Difficulty

Moderate to Advanced. Installation requires shutting off the gas, removing the burner or manifold to access the orifice, threading in the correct spud, and performing a leak and combustion check. Because it directly affects combustion safety, this repair should be handled by a licensed HVAC technician.
