BT5-4666 12V A/C Compressor – Sanden SD7H15HD, KC Head, Direct Long Mount

Description

Overview

The BT5-4666 Sanden SD7H15HD compressor is designed for 12V mobile air-conditioning systems where durability, compatibility, and service life are critical. Its direct-long mounting style supports rigid, OEM-style installation on buses, trucks, and specialty equipment.

At the same time, the KC head configuration with #8 and #10 male insert O-ring ports allows clean hose routing and reliable sealing. Because it uses PAG100 oil and a long-key shaft design, this compressor integrates seamlessly into existing SD7H15HD systems while maintaining long-term reliability.
