74R3347 Inline Receiver Drier with Moisture Indicator – High-Capacity Mobile A/C

Description

The BTRAC 74R3347 Inline Receiver Drier protects 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 demanding operation.

This unit uses an inline configuration with #6 male O-ring inlet and outlet connections, which allows direct installation into common mobile A/C hose layouts. In addition, the built-in moisture indicator provides a fast visual check of desiccant condition, so technicians can quickly determine when service is required.

The cylindrical body measures 3 inches in diameter and 9-1/4 inches in overall length. Therefore, it delivers high-capacity desiccant performance, making it well suited for systems that operate under long duty cycles. At the same time, the side-mounted pressure-relief feature adds protection during abnormal pressure events caused by high ambient temperatures or heavy system load.

Based on confirmed configuration and validated interchange usage, the 74R3347 is used in International Harvester® mobile HVAC applications. Because these vehicles often operate in demanding environments, this receiver drier provides dependable moisture control and long-term A/C system reliability.
