O-RING - HYDRAULIC UNIT (Hyundai HNZGAQ3122)

A damaged O-ring in a hydraulic unit can cause fluid leaks that reduce system pressure and lead to erratic operation. During inspection, a worn O-ring may appear cracked, flattened, or brittle from age or chemical exposure. The O-ring’s primary mechanical function is to create a static seal between two mating surfaces, preventing pressurized fluid from escaping. Keeping this seal in sound condition helps avoid contamination of the hydraulic fluid by external debris. This aftermarket replacement part references the Hyundai catalog number HNZGAQ3122. It ships at approximately 0.006 pounds. Verify the serial number or application, then call (562) 693-7748.
