BT5-4626 12V Heavy-Duty A/C Compressor – SD7H15HD, Direct Long Mount, 2-Groove 132 mm, JD Head

Description

Overview

The BT5-4626 SD7H15HD compressor is engineered for 12V mobile air-conditioning systems where durability, serviceability, and belt stability are critical. Because of its direct-long mounting design, the compressor integrates cleanly into OEM and aftermarket brackets used across heavy-duty platforms.

At the same time, the dual 1/2-inch belt drive and 132 mm clutch support higher belt loads and consistent power transfer. Additionally, the JD-style cylinder head with vertical #8 / #10 male insert O-ring fittings allows for clean hose routing in confined engine bays. As a result, the BT5-4626 serves as a dependable replacement solution across multiple heavy-duty applications.
