O-RING (Hyundai HNXKBN-04204)

HNXKBN-04204: A damaged retaining ring can allow assembled components to separate unexpectedly, leading to mechanical failure. During inspection, a retaining ring may show signs of deformation or cracking that compromise its holding force. This aftermarket replacement part references Hyundai as the OE maker and cross-references part number HNXKBN-04204. The retaining ring functions as a mechanical fastener that seats in a groove to secure parts in position. A common failure consequence is that a worn ring can no longer retain its load, causing disassembly under normal operating conditions. Keeping a retaining ring in sound condition helps prevent unintended movement of adjacent components. Verify the serial number or application, then call (562) 693-7748.
