The Sulzer ZV40/48 diesel engine incorporates precision components like the screw plug for exhaust piping, designated by code K 81258. This critical part ensures a secure and leak-proof seal within the exhaust piping system, effectively maintaining the structural integrity and preventing exhaust gas leakage. Designed to withstand extreme temperatures and pressures, the screw plug contributes to the efficient evacuation of exhaust gases, minimizing backpressure and optimizing engine performance. Regular inspection and timely replacement of the screw plug are essential to uphold the engine's reliability and ensure safe operation in challenging maritime and industrial conditions.
