O-RING (Hyundai HN3929820)

HN3929820: A damaged retaining ring can allow components to separate during operation, leading to mechanical failure. This aftermarket replacement part references Hyundai as the OE maker and cross-references part number HN3929820. The retaining ring functions as a fastener that holds assembled parts in a fixed position on a shaft or bore. A plain mechanical function is to seat into a groove and prevent axial movement of the installed component. A concrete generic failure consequence is that a worn or broken ring may cause the retained part to dislodge, resulting in sudden loss of function. Keeping a retaining ring in sound condition helps maintain secure assembly under normal working loads. Verify the serial number or application, then call (562) 693-7748.
