MTX-R SIDEMOUNT SET

High-performance two-stage regulator engineered for cold-water diving, offering robust construction, advanced thermal management, and flexible hose routing.

First Stage

• Available in yoke or DIN configuration.
• Suitable for cold water use (below 10°C / 50°F).
• Over-balanced diaphragm design: medium-pressure gas in the hose increases faster than ambient as the diver descends for superior performance at depth.
• Over-moulded endcap and environmental diaphragm with a forged first-stage body and heat-exchanging ribs for maximum thermal performance.
• 5th 3/8" UNF medium-pressure port with a protective bumper when not in use.
• Angled high-pressure ports for optimal hose routing and transmitter fitting.
• Forged rotating turret with medium-pressure ports in a parallel direction for improved hose orientation.
• Ribbed diaphragm clamp to enhance 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, mixtures above 21% O₂ require 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 and formed chrome-plated brass plate for improved durability.
• Large protective elastomer bumpers on the top and sides to prevent impacts and scratches.
• Reversible design for left- or right-hand gas supply configuration.
• Patented heat exchanger surrounding the valve to dissipate cold from gas expansion while drawing in ambient warmth.
• Comfo-bite mouthpiece.
• Double swivel, flexible nylon-braided hose for improved cold-water performance and freedom of movement.
