National Oil Seals - Wheel Seals, Redi Sleeves, Steel Hub Caps, Tools



National® Oil Seals delivers premium-quality, no-compromise solutions for every wheel end repair. Engineered for performance, these seals provide the ideal combination of technology and coverage to meet O.E. configurations for virtually all applications.

National Oil Seals help increase wheel-end reliability by aggressively deflecting dirt, moisture and other contaminants.

Featuring exclusive National® Dynamic Edge® technology, a patent-pending innovation that deflects contaminants from the seal and other wheel-end components. The National Dynamic Edge design consists of an integral patent-pending sinusoidal wave that generates a dynamic pumping action to move environmental contaminants away from the seal face.

This technology is designed to offer maximum contaminant exclusion for the toughest application. This innovation will help fleets and owner-operators eliminate another leading cause of premature seal and bearing failure.

The end result is maximum protection and longer life under even the most grueling environmental conditions.
