Own your environment with the MTX-RC scuba diving regulator. Combining rugged, military grade engineering with the supersmooth breathing experience that Apeks regulators are renowned for, the MTX-RC is the regulator that dives your way.

Featuring the same freeze-resistant technology enjoyed by the whole MTX-R range, the MTX-RC resists freeflows in even the coldest temperatures, while offering the user the additional flexibility to dial it up for a comfortable breathe in less extreme environments.
All this is achieved using an innovative first stage design that protects the regulator from freezing and a full set of user controls on the second stage to adjust the breathing performance based on the diver’s individual needs.

First Stage:

• 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 at a faster rate than ambient. This results in superior performance at depth.
• Over-moulded innovative endcap and environmental diaphragm, a forged 1st 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 performance. 
• Angled HP ports for optimal hose routing and fitting of transmitters.
• Forged rotating turret with medium pressure ports in a parallel direction 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 (European Union), within the EU anything 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 durability of the second stage.
• Large protective elastomer bumpers on the side and on the top to protect the second stage from impacts and scratches in the most vulnerable places.
• Reversible second stage for either a left or right hand gas supply configuration.
• A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water.
• Comfo-bite mouthpiece
• Double swivel hose
• Flexible nylon braided hose has better cold water performance than traditional rubber hose.
• Venturi control.
• Breathing resistance control.
