BT4-7161 Receiver Drier – Male O-Ring, Sight Glass, Dual Schrader

Description

The BTRAC BT4-7161 Receiver Drier protects mobile and heavy-duty air conditioning systems by removing moisture, acids, and debris from the refrigerant circuit. Because of this, it helps reduce corrosion, stabilize system performance, and extend compressor life.

This receiver drier cross-references MEI Corporation 7161 and uses male O-ring connections for secure sealing. In addition, a top-mounted sight glass allows quick visual inspection during service. The unit also includes two Schrader valves, which support charging, evacuation, and diagnostic work without added adapters.

Furthermore, the BT4-7161 fits well in fleet, vocational, and off-highway HVAC systems where service access matters. Since technicians often need fast checks and clean connections, this configuration improves service efficiency while maintaining system reliability.

The Flex Airbook references this receiver drier style for heavy-duty mobile A/C architectures. Therefore, the BT4-7161 works well with R-134a refrigerant and common mobile A/C lubricants used in these systems.
