Nordyne 01-1313 Bi-Flow Filter Drier 3/8" ODF Heat Pump Replacement

The Nordyne 01-1313 is a genuine OEM bi-flow filter drier designed for use in heat pump and reverse-cycle refrigeration systems. With a 3/8" ODF (Outside Diameter Flare/Sweat) connection size, this filter drier is engineered to operate efficiently in both the cooling and heating modes of a heat pump — where refrigerant flow direction reverses depending on the operating cycle.

Key Features:

• Bi-directional (bi-flow) design allows refrigerant to flow in either direction without restriction
• 3/8" ODF connection for reliable, leak-free installation
• Removes moisture, acid, and particulate contaminants from the refrigerant circuit
• Protects the compressor and system components from corrosion and wear
• Genuine Nordyne OEM replacement part — ensures proper fit and function
• Compatible with common refrigerants used in residential and light commercial heat pump systems

Bi-flow filter driers are a critical component in heat pump systems, placed in the liquid line to keep the refrigerant clean and dry during both heating and cooling operation. Replacing a worn or saturated filter drier as part of any sealed-system repair helps restore system efficiency and extend compressor life. This part is also sold under the Nordyne family of brands including Intertherm, Miller, and Gibson.
