Useful Information

Description and Purpose:

This OEM Haldex Single-Cylinder Air Brake Compressor provides consistent pressurized air to the brake system and auxiliary components in commercial diesel vehicles. Part Number: 4123520250X. Condition: New. Specifically designed for OM904 and MBE900 engines, it delivers efficient air compression performance while maintaining reliability under high-duty cycles.

Why Replacement is Important:

Over time, compressors lose efficiency or may fail due to seal wear or internal damage. Replacing a worn unit ensures your vehicle’s air system builds pressure reliably and meets safety requirements.

Impact on Vehicle Performance:

A new compressor helps restore optimal air supply for brake functions, reducing the risk of pressure loss and brake lag—especially crucial for heavy-duty trucks using OM900 series diesel engines.

Manufacturer Information:

Haldex® specializes in innovative brake and air suspension solutions for commercial vehicles, delivering reliable performance, safety, and efficiency across demanding transport and trailer applications.
