What It Helps Address

• Transmission or torque-converter fluid seepage at the seal surface
• Wear-related leakage around the shaft or housing bore
• Seal replacement during driveline service on classic Ford, Mercury, and Jaguar vehicles
• Fitment issues caused by incorrect inside diameter, outside diameter, or width
• Service needs on Borg-Warner, Tremec, Ford MX, Ford FX, and related listed transmissions

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation. Clean the bore and shaft surface thoroughly, and inspect for scoring or corrosion that can shorten seal life. Confirm the transmission or driveline configuration listed for your vehicle, since fitment varies by year, make, model, and transmission type. For example, Ford Mustang and Mercury Cougar applications require the specified spline and transmission combinations shown in the fitment data.

Quality Assurance

National has built its reputation on sealing products for more than 75 years, and this part reflects that experience with modern material selection and application-specific dimensions. The Redi-Coat surface treatment and nitrile construction support consistent sealing performance in the listed applications.
