The Champ Seals e-Barrier Wheel Seal can be installed by hand, other manufacturer’s tools or any other tool that can fit the seal into the hub. A multi-zone labyrinth design in the e-Barrier seal provides the most effective protection against dirt, grit, water and ice. The combination of low profile sections, right angle corners, low friction barrier, two rubber wipers and a specifically formulate water proof grease to both lubricate and keep water out, ensures that this seal will perform without any ‘run-in’ period.
