The gasket, code 06.56936-2355.0, serves as a vital sealing interface in the MAN L21/31 engine, preventing leakage of oil, coolant, and combustion gases between joined surfaces. Engineered from heat- and pressure-resistant materials, this gasket ensures tight, stable sealing under continuous high-temperature operation and dynamic load conditions. By maintaining system integrity and preventing contamination between engine circuits, it plays a direct role in operational efficiency, environmental compliance, and reduced maintenance requirements.
