74R1856 Inline Receiver Drier with Schrader Port – High-Capacity Mobile A/C

Description

The BTRAC 74R1856 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 steady cooling, and extends compressor life in demanding operating environments.

This receiver drier uses an inline configuration with #6 male O-ring fittings, which allows clean integration into common mobile A/C hose layouts. In addition, the Schrader service port provides convenient access for evacuation, charging, and diagnostics. Because of this, technicians can service the system efficiently without disturbing hose routing.

The high-capacity cylindrical body measures 2-3/4 inches in diameter and 10 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 side pressure-relief feature adds an extra layer of system protection during high-load operation.

Based on confirmed OEM references shown on the image and validated interchange usage, this receiver drier is commonly used on Peterbilt®, Mack®, and Western Star® truck platforms. Because these vehicles operate under long duty cycles, the 74R1856 delivers reliable moisture control and long-term durability.
