The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud engineered for the GMS951155DXA gas furnace and other GMS95-series units. The orifice meters the precise flow of natural gas into each burner, setting the correct BTU input and ensuring clean, efficient combustion. A worn, corroded, or incorrectly sized orifice causes poor flame, sooting, delayed ignition, or reduced heat output.
The genuine OEM orifice is factory drilled to the exact bore diameter required for this furnace's rated input at standard natural-gas pressure — critical for safe, code-compliant operation. Generic orifices may have inconsistent bore sizing that alters the gas rate and combustion quality. Because orifice sizing directly affects safety and efficiency, we strongly recommend the OEM part.
Rated 3 of 5. Shut off the gas supply and power, remove the burner assembly or manifold as required, thread out the old orifice, and install the new spud without over-tightening. Restore gas, leak-test every joint with soap solution, and verify manifold pressure and flame quality. This work should be completed by a licensed HVAC/gas technician.
Improper gas-orifice installation can create a fire or carbon-monoxide hazard. Professional installation is required.
