National Oil Seals has been delivering quality replacement parts for more than six decades, and our brand name is trusted worldwide. As an OE supplier, we do in-house engineering and design. That means we can guarantee the correct sealing compounds and the right designs for your application.

Federal-Mogul also has pioneered the design and use of polytetrafluoroethylene (PTFE) oil seals for commercial-vehicle wheel end applications. The company’s patented lay-down sealing lip design ensures long life in spite of extreme temperatures, shaft imperfections, shaft/bore misalignment and excessive shaft thrust or movement.

In addition, National Oil Seals offers the proprietary RediCoat sealant to eliminate bore leakage.
