The sealing ring, identified by code number H 27223, is a vital part of the sealing systems in the ASL25 diesel engine. Its main function is to prevent fluid or gas leakage between engine components, thus preserving internal pressure and protecting critical areas from contamination. Manufactured from durable, heat-resistant materials, the sealing ring ensures tight, lasting seals even under high-temperature and high-pressure conditions. Proper installation and inspection of this component are key to maintaining optimal engine performance and preventing costly breakdowns.
