ARB engineers are constantly checking and re-checking their products for ways to improve their design. In May 2009, they made a few small changes to the familiar bulkhead design.

Benefits of the new design include:

  1. No need for the FERRULE or the INNER SUPPORT TUBE in the kit, and therefore there are less total parts.
  2. Tube can be repaired without consumable parts (FERRULE and INNER SUPPORTTUBE) and therefore the new design offers far easier in-field serviceability.
  3. No tear-through failures off-road if the tube is snagged and pulled sharply off to the side.
  4. Less parts to install means a quicker install time.
  5. Easier to set-up because no exact compression nut torque is required to form a seal.
  6. Will retrofit into any current ARB 3.5mm bulkhead fitting without removing the diff.
  7. New design is identifiable by the 3 notches in each of the 2 new fittings.

From May 1st 2009 all Air Lockers (ie. all Air Lockers with serial numbers 09050000 and higher) come with the revised bulkhead kit (ARB# 170111).

The 170105 kit was the predecessor to the 170111. These work with the 3.5mm copper seal housing line. That airline is bright and malleable. The 170102 kit is for the older, 3/16 steel seal housing airline.
