The O-ring identified by code number K 27056 is a small yet essential sealing component used in conjunction with nut K 27039 in the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 diesel engine. Its primary role is to provide a tight, leak-proof seal that prevents oil or gas leakage at high pressure points, ensuring the reliability and safety of the engine's internal systems. Made from durable, heat- and chemical-resistant materials, this O-ring contributes to the engine’s overall efficiency and longevity. Regular inspection and replacement of this part are crucial in maintaining optimal sealing performance under demanding marine and industrial conditions.
