Lennox 57W93 Furnace Orifice 1.20 Inches Blue

Product Description

The LENNOX 57W93 is a replacement gas orifice for residential and light commercial gas furnaces. The orifice is a precision-drilled fitting that meters the flow of gas into the burner assembly, directly affecting combustion efficiency and flame characteristics. Proper orifice sizing is critical to safe operation and rated BTU output. This blue-coded orifice measures 1.20 inches and weighs approximately 0.1 pounds. It is installed by licensed HVAC technicians during routine service, fuel conversion, or burner replacement procedures.

This orifice is suited for gas furnace burner assemblies where an OEM-spec replacement fitting is required. Color coding on furnace orifices typically indicates gas type and drill size, allowing technicians to quickly confirm correct fitment during installation. This part is appropriate for use in applications requiring a 1.20-inch blue-coded orifice in standard furnace burner configurations.

Key Features

• Blue color coding for quick visual identification of gas type and orifice size
• 1.20-inch orifice size for precise gas metering at the burner
• Lightweight at 0.1 pounds for easy handling during service
• OEM-style replacement designed for gas furnace burner assemblies
• Precision-drilled to maintain consistent gas flow and combustion performance

Compatibility

Designed as an OEM-style replacement orifice for use in residential and light commercial gas furnace burner assemblies requiring a 1.20-inch blue-coded fitting.

Installation Notes

Installation should be performed by a licensed HVAC technician. Always shut off the gas supply and disconnect electrical power to the furnace before servicing burner components. Verify the orifice size and gas type match the furnace rating plate and local gas supply before installation. Follow all applicable local codes and the manufacturer service instructions during replacement.
