This kit is suitable for the XTX50 & XTX40 regulator 1st stages (DST type) and cannot be used on other Apeks 1st stages. It has been developed to offer another position for hose routing for technical divers. This hose position is preferred by some divers.

This is the ORIGINAL kit by Apeks is to modify the DST 1st stage, so that there is a 5th port for excellent hose routing.

Pictures of the Apeks DST is an example of how it looks like when installed. This product is just the Apeks 5th Turret Kit alone, without the Apeks DST 1st stage.
