O-RING (Hyundai HNCO0423)

HNCO0423: A damaged retaining ring can allow assembled components to separate under load, leading to mechanical failure. During inspection, a retaining ring may show signs of deformation or cracking that compromise its holding force. The retaining ring's plain mechanical function is to seat in a groove and secure a shaft or bore assembly. A concrete generic failure consequence is that a broken ring can release a retained part, causing sudden disassembly and potential damage. Keeping a retaining ring in sound condition helps maintain the axial position of components in rotating or static assemblies. This aftermarket replacement part references Hyundai as the OE maker and carries the cross-reference part number HNCO0423. Verify the serial number or application, then call (562) 693-7748.
