Detailed Description

National 472287 is an oil seal designed around exact dimensional requirements: 1.375-inch shaft diameter, 2.110-inch outside diameter, and 0.312-inch width. Those measurements make it a practical choice when replacing a worn wheel seal in axle and hub service, especially when the original seal must match the housing bore and shaft dimensions closely. National has focused on sealing solutions for more than 75 years, and this part reflects that experience with a straightforward, service-ready design.

This part cross-references Dorman - HELP 46128 and 47057 for the same application. It is also commonly searched in wheel seal replacement work for vehicles such as Ford F-150 and Chevrolet Silverado when the correct axle seal dimensions are required.

What It Helps Solve

• Oil seepage at the wheel end or axle seal area
• Contamination entering the hub or bearing area
• Seal wear from age, heat, and road exposure
• Loss of sealing performance after axle or hub service
• Dimensional mismatch when replacing a worn wheel seal

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation. Clean the bore and shaft sealing surface thoroughly, and inspect for grooves, corrosion, or scoring that could affect seal life. Press the seal in squarely to avoid distortion, and confirm the seal lip seats evenly after installation. For fitment-based searches, this part is commonly used in wheel seal replacement work on Ford F-150 and Chevrolet Silverado applications where the listed dimensions match the original seal.
