The flange K 67004 is a structural connection component designed to join air branches K 67002 and K 67003 within the Sulzer ZV40/48 air charging system. Its primary purpose is to provide a secure, accurately aligned, and leak-tight connection between adjoining airflow components, ensuring stable pressure conditions and uninterrupted air distribution. Engineered for continuous exposure to vibration, thermal cycling, pressure variations, and mechanical loading, the flange is manufactured from durable, corrosion-resistant materials suitable for heavy-duty diesel engine applications. Precision-machined contact surfaces and dimensional accuracy ensure proper assembly and effective sealing performance. The flange also facilitates maintenance and replacement procedures by providing a reliable mechanical interface between major intake system components. By preserving airflow integrity and structural stability, the K 67004 flange supports efficient turbocharging, optimized combustion, and dependable long-term engine operation.
