The compensator H 81168 is a functional mechanical element used in the Sulzer ASL25 engine to absorb dimensional changes caused by thermal expansion, vibration, or alignment tolerances within connected systems. By allowing controlled movement while maintaining system integrity, this compensator reduces mechanical stress on adjacent components and piping. Designed for durability and operational stability, H 81168 helps prevent fatigue damage, improves reliability of connected assemblies, and contributes to smoother long-term engine operation.
