74R2537 Receiver Drier with Schrader Port – High-Capacity Mobile A/C

The BTRAC 74R2537 Receiver Drier helps protect mobile air conditioning systems by removing moisture and debris from the refrigerant circuit. As a result, it reduces internal corrosion, protects compressors, and supports stable cooling performance over time.

This receiver drier uses #6 male O-ring inlet and outlet connections, which allow direct installation into common heavy-duty A/C hose assemblies. In addition, the integrated Schrader port provides convenient access for service and diagnostics. Because service access matters during maintenance, this feature helps simplify system checks.

The cylindrical body measures 3 inches in diameter and 6-1/4 inches in overall length. Therefore, it fits well in compact HVAC layouts while still delivering high-capacity moisture removal. At the same time, the unit includes a pressure-relief feature, which supports system safety during abnormal pressure conditions.

Mobile A/C systems often operate under vibration, heat, and long duty cycles. Because of this, dependable moisture control remains critical. The 74R2537 provides that protection while maintaining a compact and service-friendly design.
