The packing identified by code K 71040 is a sealing element placed between the cover K 71039 and the engine structure. Its primary function is to prevent fluid leakage and ensure pressure retention in areas exposed to oil, water, or gases. Made from resilient and heat-resistant material, this gasket plays a small but essential role in maintaining the operational integrity of the Sulzer ZV40/48 engine, particularly under varying thermal and mechanical stresses.
