National Oil Seals
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.
