SEAL - WIPER (Hyundai HN303-18)

HN303-18: A worn wiper seal can allow contaminants into the sealing area, leading to accelerated component wear. This aftermarket replacement part references Hyundai as the OE maker and cross-references part number HN303-18. The wiper seal functions by scraping debris from a moving rod or shaft as it retracts. Its primary mechanical role is to prevent external dirt and moisture from entering the sealed cavity. Over time, a failed wiper seal may cause fluid leakage or surface scoring on the rod. Keeping a wiper seal in sound condition helps maintain system cleanliness and prolongs seal life. Verify the serial number or application, then call (562) 693-7748.
