The seal ring with code 06.56200-0724.0 is a critical component for maintaining airtight and leak-proof connections within the MAN L21/31 engine. Typically used in high-pressure areas such as cylinder interfaces or fluid line couplings, the seal ring prevents the escape of oil, coolant, or combustion gases. Its resistance to heat, pressure, and chemical corrosion makes it essential for maintaining system integrity and ensuring long-term operational efficiency and safety in demanding marine or industrial environments.
