74R2668 Inline Receiver Drier with Dual Schrader Ports – High-Capacity Mobile A/C

Description

The BTRAC 74R2668 Inline Receiver Drier protects mobile air conditioning systems by removing moisture and debris from the refrigerant circuit. As a result, it helps prevent corrosion, supports stable cooling, and extends compressor life in demanding operating environments.

This receiver drier uses an inline configuration with mixed #6 O-ring fittings, including one male and one female connection. Because of this layout, it integrates easily into HVAC systems that require gender-specific hose connections. In addition, the unit includes two Schrader service ports, which provide flexible access for evacuation, charging, and diagnostics.

The high-capacity cylindrical body measures 3 inches in diameter and 8-3/8 inches in overall length. Therefore, it provides increased desiccant volume for systems with longer hose runs and higher refrigerant charge. At the same time, the top-mounted pressure-relief feature adds an extra layer of protection during abnormal pressure conditions.

Based on confirmed OEM references shown on the image and validated interchange usage, this receiver drier is commonly used on Peterbilt® and Freightliner® truck platforms. Because these vehicles operate under long duty cycles, the 74R2668 delivers dependable moisture control and service flexibility.
