The sealing ring with code number H 27219 is a key component designed to prevent leakage of fluids or gases in the ASL25 engine’s assemblies. It is typically used at joints or interfaces where pressure and temperature fluctuations are frequent, requiring resilient and durable sealing performance. Made from high-quality materials resistant to wear, oil, and thermal degradation, the sealing ring ensures operational integrity and system efficiency. Regular inspection and timely replacement help maintain reliable engine operation and avoid contamination or fluid loss.
