Detailed Description

National 8133S is a precision wheel seal in the National 8000 series, designed around the dimensional requirements of the application. With a 1.362-inch inside diameter, 2.195-inch outside diameter, and 0.250-inch width, it is sized for rear outer sealing service where the shaft and housing interface must remain clean and properly lubricated. The nitrile sealing material and Redi-Coat surface treatment support consistent contact at the sealing lip. This part cross-references Bosch 13500 and Centric Parts 417.63018 for the same application. National 8133S is a direct-fit option for 1962-1964 Chrysler Newport, 1962-1964 Chrysler New Yorker, 1962-1964 Chrysler Town & Country, and 1963-1964 Chrysler 300 rear outer positions.

What This Seal Helps Address

• Oil leakage at the wheel or axle seal area
• Contamination entering the sealed hub or axle assembly
• Worn or hardened seal material causing poor sealing contact
• Noise or service issues related to inadequate lubrication retention
• Replacement needs during rear axle or hub service on Chrysler 300, Newport, New Yorker, and Town & Country models

Installation Notes and Tips

Verify shaft diameter, housing bore, width, and position before installation. Clean the sealing surface and inspect the shaft for wear, scoring, or corrosion that could affect seal life. Confirm rear outer placement on the vehicle and match the seal dimensions to the original part before assembly. National 8133S is listed for 1962-1964 Chrysler Newport, 1962-1964 Chrysler New Yorker, 1962-1964 Chrysler Town & Country, and 1963-1964 Chrysler 300 rear outer applications.
