The protecting cap with code 11.01251-0048.0 is designed to shield exposed engine components or connection points on the MAN L21/31 engine from contamination, mechanical damage, and environmental influence. Commonly used during operation, maintenance, or storage, this cap helps prevent the ingress of dust, moisture, and debris. Its durable construction contributes to preserving component condition, reducing wear, and supporting safe and efficient maintenance procedures in marine and industrial settings.
The Teflon ring with code 11.01299-0128.A is a precision sealing component used in the MAN L21/31 engine where low friction, chemical resistance, and thermal stability are required. Thanks to the inherent properties of PTFE (Teflon), this ring offers excellent resistance to wear, high temperatures, and aggressive fluids. It is typically applied in dynamic or sensitive sealing areas, where it helps ensure smooth movement, reliable sealing performance, and extended service intervals.
The round seal ring with code 06.56936-1507.A is a critical sealing element in the MAN L21/31 engine, designed to prevent leakage of oil, fuel, or cooling media between connected components. Manufactured from high-quality, resilient materials, it provides reliable sealing under fluctuating pressures, temperatures, and vibration. Its ability to accommodate minor movements and thermal expansion helps maintain system integrity, reduce fluid losses, and support stable long-term engine operation in demanding marine and power generation environments.
The flame retardant H 86027 is a safety-critical protective component used in the Sulzer ASL25 engine to limit flame propagation and enhance fire safety in high-risk areas. Engineered to withstand elevated temperatures and exposure to combustible environments, this component provides an effective barrier against flame spread. Its robust, heat-resistant material supports compliance with fire-safety requirements and plays an important role in protecting personnel, equipment, and surrounding systems in marine and industrial engine installations.
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.
The pump rotor N 73111 is a precision-engineered rotating component designed for right-hand rotation in the Sulzer ASL25 engine’s pump system. Responsible for generating stable flow and pressure, this rotor ensures efficient fluid transfer under continuous operation. Manufactured with tight dimensional tolerances and balanced geometry, it minimizes vibration, reduces internal losses, and supports smooth pump performance. Its robust construction and wear-resistant surfaces contribute to long service life, reliable operation, and consistent system efficiency in demanding marine and industrial environments.
