Apeks new 5th port.
The picture shows a hose attached to the new port positioned at the turret end of the Dry Sealed Turret (DST) 1st stage.

The kit AP0274 is only suitable for the DST 1st stage 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. We can upgrade a new or existing DST 1st stage to include this feature.
