BT5-46122 12V TM16HD/HS A/C Compressor – Ear Mount, 8-Groove 125 mm, C Head

Description

Overview

The BT5-46122 TM16HD/HS compressor is designed for 12-volt mobile A/C systems that demand higher displacement than TM15 platforms while maintaining a compact, serviceable form factor. Because of its ear-mount design, this unit provides stable mounting in high-vibration environments commonly found in on-highway, vocational, and auxiliary HVAC installations.

At the same time, the 8-groove serpentine clutch ensures reliable belt engagement under continuous operating conditions. Additionally, the C-style O-ring pad head allows for clean hose routing in both OEM and aftermarket configurations. As a result, the BT5-46122 serves as a dependable replacement solution across multiple platforms.
