74R3456 Inline Receiver Drier with R-134a Charge Port – High-Capacity Mobile A/C

Description

The BTRAC 74R3456 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 stable cooling performance, and extends compressor life during demanding operating conditions.

This unit uses an inline configuration with female O-ring connections on both the inlet and outlet. Specifically, it features a 7/8″ female O-ring inlet and a 5/8″ female O-ring outlet, allowing direct integration into compatible IHC / Navistar HVAC hose layouts. In addition, the built-in R-134a charge port provides convenient access for system charging and service without adding external fittings.

The cylindrical body measures 3 inches in diameter and 9-1/2 inches in overall length. Therefore, it delivers high-capacity desiccant performance, making it well suited for mobile A/C systems that operate under long duty cycles or higher refrigerant volumes. At the same time, the integrated pressure-relief feature adds protection during abnormal pressure events caused by heat or heavy system load.

Based on confirmed configuration and validated interchange usage, the 74R3456 is commonly used in IHC / Navistar® mobile HVAC applications, where durability, service access, and moisture control remain critical.
