O-RING (Hyundai HNCO0423A)

HNCO0423A: A damaged retaining ring can allow assembled components to separate unexpectedly during operation. This aftermarket replacement part references Hyundai as the OE maker and carries the cross-reference number HNCO0423A. The retaining ring functions as a mechanical fastener that seats into a groove to hold parts in axial position. If the ring loses tension or breaks, the retained component may shift or dislodge, leading to operational failure. A common context for this part is securing a shaft or bore assembly where axial retention is critical. Verify the serial number or application, then call (562) 693-7748.
