The O-ring H 27106 is a critical sealing element used in the Sulzer ASL25 engine to provide a leak-free interface in fluid and pressure connections. Manufactured from elastomer specifically selected for resistance to oil, temperature fluctuations, and vibration, this O-ring maintains elasticity and sealing efficiency throughout extended service life. By preventing fluid loss and protecting internal components from contamination, H 27106 plays an essential role in preserving system integrity, ensuring operational safety, and supporting consistent engine performance.
