OIL RING - PISTON (Hyundai HNXKDE-01348)

HNXKDE-01348: A worn retaining ring can allow the piston assembly to separate under load, leading to sudden mechanical failure. This aftermarket replacement part references Hyundai as the OE maker and carries the cross-reference number HNXKDE-01348. The retaining ring functions as a mechanical fastener that secures the piston within its bore. A common failure consequence is that a broken ring may cause the piston to shift, resulting in loss of compression or internal damage. During routine service, a technician might find the ring cracked or deformed from repeated thermal cycling. Verify the serial number or application, then call (562) 693-7748.
