Nissens 64-53-6-907-402 A/C Receiver Drier Desiccant Element

The Nissens 64-53-6-907-402 is a replacement A/C receiver drier engineered to OE standards for BMW vehicles. This cartridge-style desiccant element fits into the A/C condenser assembly and is a critical component of the air conditioning system's high-pressure circuit, positioned between the condenser and the expansion valve.

The receiver drier performs three essential functions: it filters particles and debris flowing through the refrigerant circuit, absorbs harmful moisture using its internal desiccant material, and stores excess refrigerant and oil. A saturated or failed drier can allow moisture to mix with refrigerant, forming corrosive acids that damage the compressor, condenser, and evaporator from the inside. Unfiltered debris and metal chips are among the leading causes of compressor failure and seizure.

Key Features:

• Manufactured and tested to OE specifications for reliable A/C system performance
• Internal desiccant material effectively absorbs moisture from the refrigerant circuit
• Integrated filter traps particles, debris, and metal chips before they reach the compressor
• Inlet and outlet ports are sealed with protective caps to prevent moisture and contamination during storage
• Cartridge-style design fits into the existing A/C condenser assembly
• Direct replacement for BMW OEM part number 64536907402

Cross-Reference Part Numbers: 64536907402, 6907402, TSP0175408, DFD05024, 509936

The receiver drier should be replaced every two years or whenever the A/C system has been opened for service. Once exposed to ambient air, the desiccant material begins absorbing moisture immediately and can become saturated quickly, making timely replacement essential to protecting downstream A/C components.
