O-RING, 3MM X 70MM I.D. (Hyundai HNXKCD-05669)

HNXKCD-05669: A worn retaining ring can allow a shaft or bore to lose its axial retention, leading to component separation. The Hyundai catalog reference HNXKCD-05669 identifies this aftermarket replacement part as an O-ring with a 3MM cross-section and 70MM inside diameter. Its primary function is to create a static seal between two mating surfaces, preventing fluid or gas leakage. A common failure consequence is that a hardened or cracked O-ring will permit gradual leakage, reducing system pressure over time. The specified dimensions are 3MM and 70MM. Verify the serial number or application, then call (562) 693-7748.
