Stainless Dust Caps featuring expansion diaphragm that help prevents water
entry from contacting air in the bearing cavity compartment.

Designed for caravans and campers to help prevent water entry through the
back seal when a hot hub enters a river crossing.

A rapidly cooling the bearing cavity causes water entry through the rear seal
in many circumstances.

 

An overfilled bearing cavity pushes grease out the rear seal when you hub
undergoing the heating process on the highway.

This grease is evident inside your drum or around the inside of your tyres.
