CM COMPRESSOR A/C Receiver Drier for Peterbilt 200–397 Trucks — OEM Fit, Moisture & Contaminant Protection

CM COMPRESSOR A/C Receiver Drier is a direct-fit replacement for a wide range of Peterbilt trucks, engineered to protect the air conditioning system by filtering moisture and contaminants.

If you own a Peterbilt 200, 270, 320–397 series truck and need a reliable way to keep your air conditioning system running efficiently, this receiver drier is built to match OEM fit and function. It removes moisture and solid particles from the refrigerant, helps maintain proper system pressure, and supports longer life for compressors and expansion valves. The unit is compatible with many common Peterbilt models and comes prepped for simple installation when replacing a worn or damaged drier.

How does this receiver drier protect my Peterbilt's A/C system?

The drier traps moisture and particulates that degrade refrigerant and corrode internal components. By adsorbing water and catching debris, it helps prevent freezing at the expansion valve and reduces wear on the compressor and other moving parts.

• Desiccant core absorbs moisture to prevent ice and corrosion.
• Filter media captures metal shavings and particulate contaminants.
• Robust housing withstands vibration and road conditions.
• O-ring compatible fittings reduce leak risk during installation.

What Peterbilt models and years does this part fit?

This CM COMPRESSOR receiver drier is listed as compatible with a broad set of Peterbilt models including classic and newer cab configurations. Check your vehicle’s part number and fittings to confirm match before purchase, or compare dimensions to your original part.

• Fits Peterbilt 200, 270, 320, 330, 335, 357, 362, 376, 377, 378, 379, 385, 386, 387, 397 models.

• Works with typical truck A/C refrigerant systems used in these models.

How easy is the installation and what should I prepare?

Installation is straightforward for technicians familiar with heavy-truck A/C service. The replacement requires proper evacuation of the system, removal of the old drier, and installation of the new unit with fresh O-rings and refrigerant charge as specified.

• Service tools: A/C recovery/evacuation machine, wrenches, torque specs as required.
• Replace O-rings and apply refrigerant oil per manufacturer guidance.
• Evacuate and recharge the system to proper refrigerant weight and pressures.
• Inspect hoses and fittings for leaks or damage while replacing the drier.

What materials and build qualities should I expect from this drier?
