457 130 69 15 Mercedes-Benz Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component in the pneumatic braking system, providing the necessary compressed air pressure for heavy commercial vehicle operations. Built with high-strength components, it is specifically engineered to meet the high air consumption demands of large engines while maintaining long-term durability under heavy-duty operating conditions.

Vehicle and engine compatibility

Designed for Mercedes-Benz CONECTO (O 345) models including the C, H, M, and UE variants, this unit is optimized for use with OM 457 hLA engines. The assembly features a water-cooled design with M16x1.5 water ports and M26x1.5 air inlet/outlet ports to ensure optimal thermal management and efficient airflow during operation.

Installation and maintenance

For successful installation, technicians should verify that the drive type and mounting interface match the existing engine configuration. This unit features through drive capability and an integrated unloader port (M12x1.5). Regular inspection of the water cooling lines and air intake paths is recommended to maintain peak performance and extend service life.

System performance and selection

Maintaining correct air pressure levels within the braking system is essential for vehicle safety. When replacing this component, ensure all connections are secured to prevent pressure drops in the pneumatic circuit.
