Multi-Purpose Seal

National 1987 High-Durability Multi-Purpose Seal

Keep your vehicle’s mechanical assemblies running smoothly and eliminate damaging fluid leaks with the National 1987 Multi-Purpose Seal. Over time, original factory seals harden, crack, and fail due to continuous friction, heat cycles, and chemical exposure, leading to dangerous oil or grease loss. This premium replacement oil seal restores optimal sealing efficiency to safeguard your drivetrain, wheel hubs, or transmission components.

Advanced Contaminant Exclusion Technology

The National 1987 seal is constructed with a rugged steel outer shell combined with a precision-engineered sealing lip. This specialized design keeps vital lubricants trapped inside the assembly while aggressively deflecting external dirt, road grime, and water. By preventing abrasive grit from slipping into moving gears or bearings, it protects your vehicle from costly premature component wear.

Key Features & Performance Benefits

• Precision Fitment: Modeled strictly after factory dimensions for a hassle-free, secure press-fit installation.
• Heavy-Duty Elasticity: High-grade rubber compounds resist deterioration from petroleum-based oils and synthetic fluids.
• Thermal Stability: Formulated to maintain its shape, flexibility, and sealing integrity across extreme operating temperatures.
• System Protection: Minimizes mechanical friction along the shaft to prevent grooving and heat buildup.

Installation and Fitment Note

For a reliable and long-lasting seal, clean the shaft and bore surfaces completely before pressing the new seal into place. Applying a thin layer of specialized lubricant or grease to the sealing lip prior to assembly is highly recommended to prevent dry startup friction. Please cross-reference your specific vehicle fitment requirements before purchasing.
