BT5-42038 Heavy-Duty A/C Compressor – TM-08HD, 12V, 6-Groove

Description

The BT5-42038 A/C compressor is built for mobile air-conditioning systems that require consistent cooling and dependable operation. Because it uses the proven TM-08HD compressor platform, it delivers steady refrigerant flow while maintaining compact size and efficient output.

In addition, the ear-mount configuration allows flexible installation across a wide range of OEM and aftermarket brackets. As a result, this compressor works well in replacement, retrofit, and custom HVAC installations.

Furthermore, the top-port layout supports clean hose routing and proper clearance in tight engine compartments. Therefore, installation time is reduced while long-term sealing reliability improves.

The BT5-42038 operates on a 12-volt electrical system and uses a 6-groove clutch designed for higher belt contact and improved torque transfer. Because it uses a single-wire electrical connection, wiring remains simple and service-friendly.
