The Apeks XTX 50 with 5th Port Turret regulator kit has been developed to offer another position for hose routing for technical divers. This hose position is preferred by some divers, with the 5th port running the inflator hose on the right post and the backup regulator on the left post. This kit has been installed and tested, so you do not have to install it yourself.

The DST first stage uses a balanced diaphragm design for high performance that does not decline at depth or as cylinder pressure becomes low. The internal springs and parts are protected against cold water by an environmental seal to help prevent ice crystals from forming that could lead to a free flow in extremely cold conditions.

The Apeks XTX 50 is a compact second stage with an inlet heat exchanger and full metal valve barrel for improved cold transfer efficiency. A venturi lever allows customised control over the airflow within the housing, directing toward the diaphragm for reduced risk of free-flowing when not in use and toward the mouthpiece for maximum airflow. An inhalation control knob allows the diver to increase the breathing effort required to open the valve if required.
