National® has built a reputation as one of the most respected names in the industry. We have offered premium sealing solutions for more than 75 years. Our design team keeps pace with the industry and provides advanced solutions for today's vehicles.

Exclusive Dynamic Edge® technology from National Oil Seals is an innovative dirt exclusion system engineered to deflect dirt and moisture away from wheel end components. The key to National Dynamic Edge® technology is a patent pending sinusoidal wave that actually creates a pumping action to aggressively push dirt away from the seal. Manufactured with dependable, abrasion resistant nitrile, the spring-loaded main lip delivers positive sealing with reduced shaft interference. Unitized construction provides greater structural integrity, easier installation and main lip protection. For the latest technology and engineering innovation — there’s no other seal that performs like National!
