O-RING (Hyundai HNXKBN-04189)

A damaged retaining ring can lead to component separation during operation. This aftermarket replacement part references Hyundai as the OE maker and carries the cross-reference number HNXKBN-04189. The retaining ring functions as a mechanical fastener that holds assembled parts in a fixed position. A common failure consequence is that a broken or dislodged ring allows shafts or bearings to shift, causing misalignment or sudden disassembly. In a typical usage context, this ring is installed into a groove to secure a mating part against axial movement. The ring's condition directly affects the security of the assembly it retains. Verify the serial number or application, then call (562) 693-7748.
