The sealing ring for the cylinder liner (code K 21407) is an essential component in the Sulzer ZV40/48 engine, ensuring a tight and secure seal between the liner and engine block. This ring plays a crucial role in preventing coolant and combustion gas leaks, maintaining optimal pressure levels within the cylinder. Manufactured from high-quality, heat-resistant materials, it is designed to withstand extreme temperatures and pressures, ensuring long-lasting performance. Routine inspections and timely replacement of the sealing ring are essential to prevent engine inefficiencies and potential damage, ensuring the engine continues to operate at peak efficiency in demanding conditions.
