ARB Air Locker Diff Lock Seal Housing Located inside your differential housing, this ARB Air Locker seal housing is a critical component that holds the seals responsible for keeping your diff oil in and the compressed air in. It's the part the air line screws into to activate your locker. This housing often needs replacement if the original is damaged during a differential rebuild, if the O-ring sealing surfaces have been scored, or if the air line fitting thread has been stripped. Failure to replace a damaged housing will result in a significant oil leak out of the air line and a complete loss of air pressure, meaning your diff lock will fail to engage when you need it most.
