154*175*13.5 TB5Y Iron Surface Oil Seal for Nissan UD Truck Replace OE 43090-00Z00 BD4263-F0 43090-90061 Rear Axle Hub Seal

154*175*13.5 TB5Y oil seal is custom-made for Nissan UD and HINO truck hubs, directly interchangeable with OE parts 43090-00Z00. Adopting professional Japanese TB5Y structure, it features a stepped thickened one-piece stamped iron shell. It locks tightly into the hub mounting groove to avoid displacement and loosening under heavy-duty vibration. Seamless integral stamping ensures high rigidity against cracking and deformation, while rust-proof passivation provides excellent corrosion resistance for muddy and saline road environments.

Built with spring-loaded dual lips, the main lip firmly retains gear oil and compensates for shaft runout and eccentricity to stop oil seepage. The outer dust lip blocks sand, mud and debris, protecting bearings from wear and seizure.
