Federal-Mogul has introduced a National heavy-duty oil seal that’s said to offer maximum contaminant exclusion. The new National ‘Red’ 37 Series wheel seal features patent-pending Dynamic Edge technology that deflects contaminants from the seal and other wheel-end components. The design consists of an integral ‘sinusoidal’ wave that actively sweeps and propels the bad stuff away from the seal face.

The new seal also features a labyrinth design of four floating points of contact that lock out dirt and moisture and help ensure maximum service life. The spring-loaded sealing lip, manufactured from abrasion-resistant nitrile, delivers positive sealing with minimal shaft interference, the company says. The seal’s unitized construction provides increased structural integrity, and a unique inside diameter and outside diameter design – featuring Federal-Mogul’s Sure-Lock technology – further resists contamination and prevents bore and shaft leaks.
