O-ring for MAK 16M453AK

The O-ring part number 1.2123-102 serves as a sealing component within the cylinder head assembly of the MAK 16M453AK engine. It is positioned at the intake valve to establish a seal between the valve and its guide or seat, helping to prevent the escape of combustion gases and the leakage of lubricating fluids. By maintaining this seal, the component assists in preserving the internal pressure required for the intake and combustion phases of the engine cycle.

This part is compatible with the MAK 16M453AK engine model. It is designed to fit the specific dimensions required for the intake valve configuration in this engine series. The component is intended for use in large-scale diesel engines commonly found in marine propulsion and power generation applications.

O-rings in valve systems function to isolate different engine environments, such as separating the combustion chamber from the valve train or lubrication circuits. Proper sealing at these points is necessary to ensure that the engine operates within its design parameters for compression and fluid management. Regular inspection of these seals during maintenance intervals helps identify wear before it affects engine performance or leads to pressure loss.
