Apeks Regulator XTX50 Sidemount Set

First Stage
• Available in Yoke or DIN configurations.
• Suitable for cold water use (below 10°C / 50°F).
• Unique over-balanced diaphragm design – as the diver descends, the over-balancing feature allows the medium-pressure gas in the hose to increase faster than ambient pressure, resulting in superior performance at depth.
• Innovative over-moulded endcap and environmental diaphragm, with a forged first-stage body offering maximum thermal performance.
• The 5th 3/8" UNF medium-pressure port includes a protective bumper when not in use.
• Forged first-stage body with heat-exchanging ribs for maximum thermal efficiency.
• Angled high-pressure ports for optimal hose routing and transmitter installation.
• Forged rotating turret with medium-pressure ports aligned parallel for improved hose orientation.
• Ribbed diaphragm clamp for improved heat exchange in cold water conditions.
• Double-swivel hose for greater freedom of movement and comfort.
• Tested for Octopus use – EN250A cold water.
• Nitrox/Oxygen compatible – up to 40% O² outside the EU; within the EU, any mixture above 21% O² must use an M26 connection.

Second Stage
• High-performance, pneumatically balanced, lever-operated poppet valve.
• Large, diver-friendly, self-flushing, controllable purge button.
• Front cover with over-moulded elastomer incorporates a formed chrome-plated brass plate, improving the durability of the second stage.
• Large protective elastomer bumpers on the sides and top to protect the second stage from impacts and scratches in vulnerable areas.
• Reversible second stage for left- or right-hand gas supply configuration.
• Patented heat exchanger surrounding the valve mechanism, dissipating cold caused by gas expansion while drawing in warmth from the surrounding water.
• Comfo-bite mouthpiece.
• Double-swivel hose.
• Flexible nylon-braided hose provides better cold-water performance than traditional rubber hose.
