Product Details

The Lennox 41J81 is a precision-engineered #54 LP straight orifice designed specifically for Liquid Propane gas conversions and pressure regulation in residential and light commercial HVAC systems. This #54 orifice features a 0.055-inch diameter opening, optimized for Liquid Propane flow rates.

Key Features:

  • Precision calibration with #54 drill size provides exact fuel metering for LP gas applications, ensuring consistent BTU delivery
  • OEM compatibility designed as a direct drop-in replacement for Lennox units, eliminating the need for field modifications
  • Manufactured from high-grade brass to resist corrosion and thermal expansion during long run cycles
  • Proper orifice sizing prevents yellow flame conditions and reduces carbon monoxide production

This essential part helps regulate the flow of gas to the burners, ensuring optimal performance and safety. This specific orifice is calibrated for the higher pressure and density of Liquid Propane and should not be used for Natural Gas applications, as it will result in significantly underfired burners.
