The Durahub Extreme Bearing Protectors by Couplemate are engineered to allow owners to easily inspect bearing wear. In one glance, trailer owners can identify the grease condition inside the wheel hub. If containments have entered the bearing cavity, the product indicates the bearing needs to be removed and re-packed. Each unit is pre-tested under water, and can be completely submerged without corrosive damage.
