Carrier KH43LE102 Filter Drier

The Carrier KH43LE102 Filter Drier is a critical liquid line component engineered to maintain refrigerant system integrity by neutralizing moisture and capturing solid contaminants. As a Factory Authorized Part, this 083 series drier features 3/8-inch ODF sweat connections, making it a direct-fit replacement for various Carrier, Bryant, and Payne residential and light commercial units. Designed for high-pressure performance, it has a Maximum Working Pressure (MWP) of 680 PSIG, ensuring reliability in modern HFC and R-410A systems where high discharge pressures are standard. This filter drier utilizes a high-capacity solid core to prevent acid formation and technical failures in the expansion valve (TXV). Replacing a saturated filter drier like the KH43LE102 is essential during any system breach or compressor swap to protect the refrigeration cycle from premature wear. This OEM part replaces legacy numbers including KH41EZ250 and KH41LG114, maintaining the specific pressure drop and filtration standards required by the manufacturer.

Key Benefits:

• OEM Compatibility: Guaranteed fit for Carrier-family equipment, including Bryant and Payne condensing units and heat pumps.
• High Filtration Efficiency: Solid core construction effectively removes copper oxides, burrs, and moisture that lead to acid buildup.
• Standard Fitting Size: Features 3/8" ODF sweat connections for easy brazing into the liquid line.
• Pressure Resilience: Rated for 680 PSIG, making it compatible with high-pressure R-410A and R-22 retrofits.
• System Protection: Prevents TXV plugging and ensures long-term compressor reliability.

Common Questions:

When should I replace the KH43LE102 filter drier?
A liquid line filter drier should be replaced whenever the refrigerant circuit is opened for repair, or if a temperature drop across the drier exceeds 3°F, indicating a restriction.

Can this drier be used with all refrigerant types?
Yes, the KH43LE102 is designed for use with CFC, HCFC, and HFC refrigerants, including common R-410A and R-22 applications.

Is this a bi-flow drier for heat pumps?
This is a Uni-Flo liquid line drier. For heat pump applications, ensure it is installed in the liquid line where flow is unidirectional or use a dedicated bi-flow model if required by the specific piping schematic.
