O-RING (Mitsubishi MB05504-03800)

MB05504-03800: A damaged retaining ring can allow assembled components to separate unexpectedly during operation. The O-ring type retaining ring cataloged under Mitsubishi part number MB05504-03800 serves as an aftermarket replacement. Its plain mechanical function is to seat within a groove to hold mating parts in position. A concrete generic failure consequence is that a worn or missing ring may cause vibration or loosening of the secured assembly. During service, a retaining ring that has lost its tension can no longer maintain proper axial restraint. Keeping a retaining ring in sound condition helps prevent disassembly of the joined components under load. Verify the serial number or application, then call (562) 693-7748.
