National Seals Wheel Seal

The National Seals Wheel Seal functions in wheel-end assemblies that travel long regional freight loops where hubs operate for hours with minimal downtime. Its nitrile lip creates a barrier that holds lubrication inside the hub cavity even when rotation cycles rise and fall throughout the journey. The seal dimensions match wheel-end designs found in many mid-duty trailer applications, promoting consistent motion between the spindle and the bore. Its construction helps sustain hub lubrication integrity during temperature swings created by braking patterns and roadway grade changes. The National Seals 370119A contributes lasting fluid retention for vehicles performing steady freight movement across extended regional routes.
