According to Champ Seals, one of the primary reasons for premature wheel seal failures is incorrect installation of the seal. The e-Barrier features 150 percent thicker steel and a 'safety zone' feature, to allow for some distortion of the seal front face without affecting the seal performance.
A low friction bumper ensures low seal friction from the outset.
The Seal's multi-zone labyrinth design provides 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 formulated waterproof grease to both lubricate and keep water out, ensures that this seal will perform without any 'run-in' period.
