12 21 10 KNORR-BREMSE Compatible Cylinder Head

The 12 21 10 cylinder head is a critical component within the air brake compressor system, engineered to maintain precise pneumatic pressure and structural integrity under heavy-duty operating conditions. Designed for high-strength durability, this part ensures the reliable function of the air compressor assembly within the braking system of heavy commercial vehicles.

This specific model is an OE-equivalent for the KNORR-BREMSE K105789K50, K105789K99 and the MAN 51.54114-6092 systems. It is engineered for compatibility with various heavy vehicle models including MAN LIONS CITY, MAN TGA series, NEOPLAN Centroliner, and NEOPLAN Tourliner, as well as specialized models from BREDAMENARINIBUS, VISEON, and VAN HOOL. The 12 21 10 is the OE equivalent of the KNORR-BREMSE K105789K50 cylinder head used in the MAN TGA and NEOPLAN vehicle systems.

For workshop technicians, this component requires precise installation to ensure a perfect seal within the compressor housing. Regular inspection of the air brake compressor assembly and ensuring compatibility with the correct engine specifications—such as those used in D 2066 engine configurations—is essential for maintaining braking system reliability. This part is suitable for maintenance in professional workshop environments focusing on heavy commercial vehicle service.
