74R3327 Inline Receiver Drier – Freightliner New Style High-Capacity A/C

The BTRAC 74R3327 Inline Receiver Drier protects heavy-duty mobile air conditioning systems by removing moisture and contaminants from the refrigerant circuit. As a result, it helps prevent internal corrosion, supports consistent cooling performance, and extends compressor life during daily operation.

This unit is designed as a New Style receiver drier for Freightliner® HVAC systems. It replaces earlier receiver-drier configurations by using an updated port layout and service design. Because of this, it integrates cleanly into Freightliner systems that require the newer hose and fitting arrangement.

The drier uses an inline configuration with mixed #6 O-ring fittings, including a male inlet and a female outlet. Therefore, it installs correctly in applications where hose gender orientation matters. In addition, the unit includes two M10 Schrader valves, which provide convenient access for evacuation, charging, and diagnostics without altering surrounding components.

The cylindrical body measures 3 inches in diameter and 10 inches in overall length. As a result, it delivers high-capacity desiccant performance, making it well suited for Freightliner trucks that operate under long duty cycles and higher refrigerant volumes.

Because receiver driers should always be replaced when the A/C system is opened, the 74R3327 serves as a dependable service replacement when maintaining or repairing Freightliner mobile HVAC systems.
