74R2106 Inline Receiver Drier with Low-Pressure Switch – High-Capacity Mobile A/C

The BTRAC 74R2106 Inline Receiver Drier helps protect mobile air conditioning systems by removing moisture and debris from the refrigerant circuit. As a result, it supports steady cooling performance, reduces internal corrosion, and helps extend compressor life in demanding on-highway 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 unit includes a factory-installed low-pressure switch mounted on top, which helps control compressor operation by monitoring system pressure during normal use.

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 protection during high-load or abnormal pressure conditions.

Based on confirmed application information shown on the image and validated interchange usage, this receiver drier is commonly used on Freightliner® and Volvo® truck platforms. Because these vehicles operate under long duty cycles, the 74R2106 delivers reliable moisture control and integrated pressure management.
