The sleeve, code 11.41199-0005.A, is a precision-engineered component designed to provide alignment, support, and protection for mating parts within the MAN L21/31 engine assembly. Serving as a guiding or spacing element, it ensures correct positioning of adjoining components and helps distribute mechanical loads evenly across the assembly. Manufactured from durable materials capable of resisting wear, temperature fluctuations, and operational stresses, the sleeve contributes to the stability and longevity of connected parts. By maintaining precise alignment and reducing friction or vibration effects, this component plays an important role in preserving the efficiency, reliability, and service life of the engine.
The thermostat housing, code 11.41100-0565-1.A, is a key structural component of the cooling system in the MAN L21/31 engine, designed to accommodate the thermostat and manage the controlled distribution of cooling water. Precisely machined to ensure correct alignment and sealing surfaces, the housing enables accurate temperature regulation by directing coolant flow according to engine operating conditions. Its robust construction allows it to withstand pressure variations, thermal cycling, and continuous vibration typical of medium-speed diesel engines. By maintaining proper positioning of the thermostat assembly and ensuring leak-tight coolant circulation, the thermostat housing plays an important role in stable thermal management and reliable engine operation.
The O-ring, code 06.56936-2985.0, is a compact but essential sealing element used throughout the MAN L21/31 engine to ensure leak-free connections between mating components. Designed with a precisely defined elastic profile, the O-ring compresses within its groove to create a reliable seal against fluids and gases under varying pressure and temperature conditions. Manufactured from high-quality elastomer materials resistant to heat, oils, and chemical exposure, it maintains its flexibility and sealing capability over long operating periods. By preventing the escape of lubricants or coolant and protecting systems from contamination, this simple yet highly effective component contributes significantly to the operational safety and efficiency of marine and stationary diesel engines.
The seal H 85720 is an essential sealing element used in the Sulzer ASL25 engine to ensure tight sealing within oil or fluid circuits exposed to varying pressures and temperatures. Engineered for durability and chemical resistance, it prevents leakage while maintaining system pressure and protecting internal components from contamination. Its precisely manufactured geometry allows optimal contact with surrounding surfaces, ensuring consistent sealing performance even under continuous vibration and thermal stress. The reliability of the H 85720 seal is crucial for maintaining efficient engine operation, minimizing fluid losses, and supporting the long-term durability of the engine systems.
The protective cocoon H 74134 serves as a shielding component within the Sulzer ASL25 engine assembly, designed to protect sensitive mechanical elements from debris, contamination, and mechanical impacts. Its structural design provides an additional protective layer around critical components that operate under vibration and dynamic loads. Manufactured with durable material and precise dimensions, the cocoon maintains the correct spatial arrangement of adjacent elements while reducing exposure to environmental influences. By safeguarding internal mechanisms, the H 74134 cocoon enhances reliability, extends component life, and supports stable engine performance in demanding marine and industrial environments.
The seal H 82506 is a critical sealing component used in the Sulzer ASL25 engine to maintain the integrity of fluid and pressure systems operating under demanding conditions. Designed to provide reliable sealing between mating components, it prevents leakage of lubricating oil or other working fluids while protecting internal engine parts from contamination. Manufactured from high-performance sealing materials resistant to temperature fluctuations, oil exposure, and mechanical stress, this seal ensures long service life and consistent sealing performance. By maintaining stable operating conditions within the engine systems, the H 82506 seal contributes directly to efficiency, operational safety, and reduced maintenance requirements.
