  • Outside diameter: 3.165 inches (80.390 mm)
  • Thickness/width: 0.562 inches (14.270 mm)
  • Housing bore diameter: 3.160 inches (80.260 mm)
  • Material: Polyacrylate for enhanced oil resistance
  • Redicoat coating for improved corrosion protection
  • Part of the National 6000 series of sealing systems

Technical Details and Material Specifications

The 6808N differential pinion seal features a polyacrylate elastomer construction, which offers excellent resistance to gear oils and high temperatures commonly found in automotive differentials. The seal’s precise inside diameter of 1.875 inches ensures a secure fit on shafts, while the 3.165-inch outside diameter matches the housing bore for effective sealing. The 0.562-inch thickness provides durability and maintains proper sealing pressure. Additionally, the Redicoat treatment enhances corrosion resistance, extending the service life of the seal in harsh operating environments.

Compatible Vehicles and Applications

This differential pinion seal is compatible with a range of vehicles, including Chevrolet Blazer and C10 Suburban, Dodge Challenger and Charger, Ford F-100, F-250, and F-350, GMC J20 and Jimmy, as well as Jeep and Lincoln Continental models. The National 6808N is designed specifically for driveline and axle sealing needs, ensuring proper oil retention and preventing contamination in these applications.

  • Prevents oil leaks from the differential pinion shaft
  • Protects against dirt and debris entering the differential housing
  • Maintains proper lubrication for differential gears
  • Reduces risk of premature wear on driveline components
  • Helps avoid costly repairs due to seal failure

Installation Notes and Tips

When installing the National 6808N differential pinion seal, ensure the housing bore and shaft surfaces are clean and free of debris. Use appropriate tools to press the seal evenly into the housing bore without damaging the sealing lip. Verify the seal orientation matches the original installation to maintain proper oil retention. Lubricate the seal lip lightly with gear oil before installation to reduce initial wear. Check for proper fitment on the shaft diameter of 1.875 inches to avoid leaks.

Quality Assurance and Warranty

National’s 6000 series seals, including the 6808N, are manufactured to meet strict industry standards for durability and performance. The polyacrylate material and Redicoat corrosion protection contribute to long service life under demanding conditions. While specific warranty terms may vary, National products typically come with a limited warranty against manufacturing defects, providing confidence in the seal’s reliability for your Chevrolet, Dodge, Ford, GMC, Jeep, or Lincoln vehicle.
