This handy tool is used to assist the assembly and dis-assembly of the ACD (Automatic Closure Device) system featured in Aqualung yoke regulators.

With this tool, there is no longer any need to swap over between the dust cap and tank valve during service of the ACD. Just simply place the socket tool on top of the yoke nut and tighten it up with the yoke screw. The "slotted" groove allow the tool to be slid in easily and to accommodate for all various lengths of the yoke screw. 

The other component of the set is the small bushing tool that can that can be used in combination with the socket tool or stand alone in order to position and effortlessly install the o-ring inside the groove of the yoke shutter crown.

This tool fits all Aqualung models fitted with ACD.

Machined from light-weight Acetal.

Allen key is sold separately.
