11 30 21 Cylinder Head, Air Brake Compressor Repair Kits

The high-strength component serves a vital role in maintaining the pneumatic integrity of the air brake compressor system. Designed for heavy-duty service, this cylinder head ensures optimal pressure regulation and structural stability within the compressor assembly, preventing common pneumatic leaks and maintaining consistent air supply for the braking system.

11 30 21 is the OE-equivalent cylinder head used in MERCEDES BENZ CAPACITY (OM457 engine), CONECTO O345 (OM457 and OM447 engines), and CITARO O530 (OM457 engine) systems. It is engineered to meet the rigorous standards of WABCO hardware and compatible heavy commercial vehicle systems, ensuring seamless integration with existing pneumatic architectures.

Workshop technicians should perform a thorough inspection of the compressor housing and seating surfaces during installation to ensure a perfect fit. Regular maintenance of the air brake compressor system, including periodic checks of the cylinder head and valve seals, is essential for preventing system pressure drops. This part is designed for direct assembly within professional workshop environments specializing in heavy commercial vehicle service.

Proper seating of the cylinder head is critical to avoid air leaks that could affect braking response. Always verify that all gaskets and seals are in optimal condition when performing a compressor repair to ensure long-term reliability in high-pressure environments.
