It uses a proprietary PTFE lay-down bi-directional sealing lip that maintains reliable contact even during wheel end movement, combined with a triple barrier contamination system to keep dirt and moisture out. The seal operates in extreme temperatures from -100°F to 450°F and is compatible with mixed lubricants. It is typically replaced when wheel end leaks occur or during routine brake/wheel-end maintenance to prevent oil loss and bearing failure.
