BT5-51606 Compressor – Seltec / Valeo TM16HD/HS 12V R134a, 158mm 1-Groove Variable Clutch, G Head

Description

Product Description

The BT5-51606 compressor is built on the proven Seltec / Valeo TM16HD/HS platform, commonly used across truck, bus, and specialty vehicle air conditioning systems. Its 6-cylinder design and 9.7 cu. in. displacement provide strong refrigerant flow while maintaining smooth, dependable operation.

This unit is factory-charged with 180cc of PAG46 oil and configured for R134a refrigerant. The G head uses a universal O-ring pad with horizontal port orientation, allowing adaptable hose routing across a wide range of installations. A 158mm single-groove variable clutch supports legacy belt setups requiring flexible belt widths.

Because of its direct-mount design, splined shaft, and bi-directional rotation (CW / CCW) capability, the BT5-51606 offers broad application coverage in multi-fit HVAC systems.
