BT5-4608 12V Super Heavy-Duty A/C Compressor – SD7H15-SHD, Ear Mount, 1-Groove 138mm, GK Head

Description

Overview

The BT5-4608 SD7H15-SHD compressor is engineered for 12-volt heavy-duty mobile air conditioning systems, particularly in agricultural, construction, and off-road equipment where durability and vibration resistance are critical. Because of its ear 8-long mounting design, the compressor provides enhanced stability in harsh operating environments. At the same time, the single-groove, 138 mm clutch supports reliable belt engagement in traditional 1/2-inch belt drive systems.

Additionally, this unit uses a GK-style rear horizontal pad head with O-ring sealing, which allows for clean hose routing in both OEM and aftermarket installations. As a result, it integrates easily into replacement and retrofit systems. Furthermore, its clockwise rotation and Deutsch electrical connection ensure compatibility with modern heavy-duty electrical systems.
