O-Rings and Sealing Rings in a Jet Engine
O-rings and sealing rings are critical
components in jet engines, ensuring proper sealing, preventing leaks, and
maintaining system integrity under extreme conditions. These rings are used in
various engine sections, including fuel systems, hydraulic systems, and
compressor and turbine assemblies.
