e-Barrier Wheel Seals

The e-Barrier Seal has been developed using the latest technology and materials combined with 20+ years of field experience. They are manufactured in a state of the art new factory, working to the latest automotive standard, IATF 16949. With its unique and Patent Pending design features, the e-Barrier Seal addresses the two key reasons for premature failure, installation damage and entry of dirt into the seal.

Key Benefits
  • Easy to Fit - Any tool will work, even your hands.
  • Impossible to Damage during Installation.
  • Standard & Premium Versions available.
  • Unrivalled protection against contaminants.
  • Eco-friendly - low friction from the outset.
  • Matches any Warranty.
Material

Today’s wheel seals can be broadly categorized by the rubber used for the sealing lip. The material properties are keys to achieving maximum life of the seal. With these in mind, CHO have spent thousands of hours developing testing the materials. The two main option are either a Nitrile compound (NBR) or a Hydrogenated Nitrile (HNBR). To the layman this may not seem very significant, but this has a dramatic effect on the expected seal life as HNBR has some key benefits over NBR, these being:
1. Higher temperature capability, therefore the HNBR lip ages much slower.
2. Greater wear resistance, therefore increasing lip life
3. Greater compatibility to a wider range of lubricating oils, including synthetics.

We are so confident in our materials that we offer the same Warranty as the comparative competitors seals as listed in the table below.
Due to the varying conditions of different applications, and to offer the right balance of cost and required performance, the e-Barrier Seal is offered as two material options, the Standard and the Premium as shown in the table below, with the major competitors equivalent listed alongside for comparison.

Easy-Fit Tough Design
When designing the e-Barrier seal we wanted to eradicate the largest reason for premature seal failures— Installation damage. We have done this by designing the stiffest profile and using the thickest steel ever used for a seal, right at the front face. The rubber OD beads allow for the minimum fitting force required, and the low friction barrier ensures maximum transmission of the fitting forces to the Seals OD.

Low Friction Bumper
The Low Friction bumper performs 2 major functions which other seals simply have not got. Firstly, the bumper transmits the fitting force from the front of the seal to the Seal OD in a far more efficient manner than any other seal. Most other seals have a rubber bumper, which acts like a brake, thus increasing the required torque, creating excessive temperatures, and ultimately more fuel to turn the seal. This can last a few hundred hours until the rubber eventually goes hard. Secondly, the bumper acts as the first contacting defense against dirt ingress, as part of the multi-zone labyrinth protection system.

Multi-zone Labyrinth
Using the latest labyrinth technology, the e-Barrier seal provides the best protection and the lowest friction on the market. The combination of low profile section right angle corners, low friction barrier, two rubber wipers and a specifically formulated water proof grease to both lubricate and keep water out, ensures this is the best seal at keeping dirt , grit water and ice out on the market.
