UAC A/C Receiver Drier RD 6166C — Vehicle-Specific Accumulator, Desiccant Moisture Filter

The UAC RD 6166C is a vehicle-specific A/C receiver drier (accumulator) designed to protect your air conditioning system by removing moisture and filtering contaminants.

When an automotive air conditioning system circulates refrigerant, moisture and particles can damage components and reduce cooling efficiency. The UAC RD 6166C accumulator/receiver drier serves as a filtration and moisture-trapping device placed in the refrigerant circuit. Built to fit specific vehicle models, it helps preserve system performance and extend the life of compressors and valves by capturing debris and holding desiccant to absorb water vapor.

How does the RD 6166C improve A/C system longevity?

The receiver drier minimizes the risk of corrosion and internal component failure by trapping moisture and particulates before they circulate through the system. It also provides a reservoir for refrigerant to stabilize pressure and flow during operation.

• Contains desiccant to absorb water vapor
• Filters particulates that could damage expansion valves and compressors
• Acts as a refrigerant reservoir to smooth pressure changes
• Vehicle-specific fit reduces installation errors

What are the key specifications and compatibility details?

The RD 6166C is a purpose-built accumulator with UAC quality standards and is listed as a vehicle-specific fit. Confirming correct fitment against your vehicle’s OEM part number or application guide ensures proper performance and installation.

• Manufacturer: UAC
• Part number: RD 6166C
• Fit type: Vehicle specific — verify compatibility with make/model/year
• Package dimensions: 8.636 cm L × 22.86 cm H × 9.398 cm W

What should I expect during installation and maintenance?

Installation typically requires evacuation of the system and professional handling of refrigerant. Replacing the receiver drier is commonly performed when the system is opened for compressor replacement, or whenever moisture contamination is suspected.

• Install during A/C system servicing or compressor replacement
• Requires proper refrigerant recovery and vacuuming before fitting
• Follow torque and hose-connection specifications for leak-free sealing
• Inspect lines and fittings for corrosion before assembly

Who is this for: The UAC RD 6166C is intended for automotive technicians, DIY mechanics, and fleet maintenance teams who need a vehicle-specific accumulator/receiver drier to maintain reliable air conditioning operation. Choose this part when replacing a worn or contaminated drier, during A/C system overhauls, or when matching OEM-style components for accurate fit and dependable filtration.
