The seal H 16552 is a critical protective component designed to provide reliable sealing in selected interfaces of the Sulzer ASL25 engine where fluid retention and contamination control are essential. Engineered for resistance to oil, temperature fluctuations, and continuous mechanical stress, it maintains elasticity and sealing integrity throughout extended operating periods. By minimizing leakage and safeguarding adjacent assemblies from external impurities, the H 16552 seal contributes directly to reduced maintenance requirements, improved system cleanliness, and the long-term reliability of the engine’s auxiliary and main systems.
