BT5-4419 12V Heavy-Duty A/C Compressor – SD7H15HD, Direct Mount, 2-Groove 125mm

Overview

The BT5-4419 SD7H15HD compressor is engineered for 12V heavy-duty and fleet HVAC systems that utilize traditional dual 1/2-inch V-belt drives. Because of its direct long-mount design, the compressor provides rigid installation and improved stability under continuous operation. At the same time, the 2-groove, 125 mm clutch supports reliable belt engagement in legacy and mixed-platform vehicle configurations.

Additionally, this compressor uses a GV-style cylinder head with rear universal O-ring FLX-7 pad fittings, which allows for flexible hose routing across multiple OEM and aftermarket installations. As a result, it integrates easily into existing systems. Furthermore, clockwise rotation and a 1-wire Packard electrical interface with integrated diode protection ensure compatibility with standard heavy-duty compressor control circuits operating on R134a refrigerant.
