Lennox 18J16 Orifice
The Lennox 18J16 Blue Inducer Orifice is a high-precision OEM mechanical component engineered for furnace draft inducer assemblies. As a critical combustion air orifice, this part is specifically designed to regulate the air-to-fuel ratio within the combustion chamber, ensuring optimal thermal efficiency and reducing carbon emissions. This genuine Lennox furnace replacement part is constructed from durable, corrosion-resistant materials to withstand the high-temperature environment of a gas furnace inducer motor housing.
Field technicians frequently utilize the 18J16 for HVAC system diagnostics when addressing issues related to improper gas flow or pressure imbalances in the combustion circuit. Its distinct blue color-coding allows for immediate visual identification during furnace repair and maintenance. Compatible with a variety of Lennox-branded units, including the 90UGFA and G32 series, this blue inducer orifice maintains localized pressure consistency to support reliable ignition and continuous exhaust flow through the heat exchanger.
Key Benefits- Ensures a precise air-to-fuel ratio for maximized combustion efficiency.
- Direct OEM replacement part for guaranteed fitment in Lennox gas furnaces.
- Corrosion-resistant construction provides long-term reliability in harsh environments.
- Optimizes furnace draft inducer performance and stabilizes pressure.
- Simplifies HVAC repair with standard 1/2-inch mechanical specifications.
What does a blue inducer orifice do in a Lennox furnace?
The 18J16 acts as a flow restrictor within the inducer assembly, precisely metering the volume of air mixed with gas to prevent incomplete combustion.
How do I know if my Lennox 18J16 orifice needs replacement?
Technicians often check for physical obstructions, soot buildup, or cracks in the orifice that lead to pressure switch trips or poor flame quality.
Is the Lennox 18J16 compatible with other HVAC brands?
While primarily a Lennox OEM part, it is also found in equipment from Allied Air brands, including Armstrong, Concord, and Ducane, under the same part number.
