Lennox 97M75 Kit
The Lennox 97M75 Rebuild Kit is an essential field-replacement component designed for precise refrigerant metering and system restoration. This replacement RFC kit features a .057 orifice, ensuring calibrated liquid flow through the expansion device to maintain correct superheat levels and optimize evaporator coil efficiency. Engineered for high-pressure cooling environments, the assembly provides the necessary sealing integrity required to prevent localized pressure drops that can lead to compressor slugging or reduced BTU capacity.
When performing circuit repairs or manifold upgrades on compatible Lennox heat pumps and air conditioners, this 0.057 piston kit ensures the metering device matches the technical requirements of the outdoor unit's specific SEER rating and refrigerant charge. The 97M75 kit utilizes robust materials to withstand thermal cycling and high-side discharge pressures without deformation. For technicians troubleshooting restricted flow or inconsistent pressure readings, replacing the metering orifice with this factory-spec component is the industry standard for returning HVAC residential systems to their original performance parameters.
Key Benefits for Technicians:
- Calibrated .057 Orifice: Ensures precise refrigerant flow control for optimal heat transfer.
- System Compatibility: Designed specifically for Lennox HVAC equipment requiring matched piston sizes.
- Reduced Pressure Drop: Precision machining prevents turbulence-induced flash gas within the metering assembly.
- Field Reliability: High-grade construction eliminates failures common with generic aftermarket refrigerant components.
Common Technical Questions:
- How do I verify if the .057 piston is correct for my system? Always refer to the outdoor unit's charging chart or the installation manual for the specific evaporator coil match-up to ensure the .057 orifice size provides the correct pressure drop.
- Does this kit include the necessary gaskets? This RFC kit includes the primary internal components required to reseal the metering housing during the orifice swap.
- Can this be used for R-410A applications? Yes, the Lennox 97M75 is rated for the high-pressure requirements of modern refrigerant systems and the specific chemical properties of POE oils.
