The Apeks MTX-RC Single Cylinder Regulator Set is designed to be used in a long hose style single cylinder equipment configuration and is useful in situations where the large gas volumes of a twin cylinder configuration are not required.


The MTX-RC is an updated version of the original MTX-R regulator which was developed to meet the incredible tough requirements of the United States Navy Experimental Dive Unit extreme cold water test.


Apeks modified the MTX-RC to include the convenience, comfort and practicality of diver adjustable inhalation effort and venturi effect.


The MTX-RC is a high performance fully balanced regulator system much like the majority of the Apeks range. It was developed for extreme cold conditions and with technical / advanced diving in mind.


The package includes:

  • 2 x MTX-RC Primary second stages
  • 1 x MTX-RC first stage
  • 1 x 2.1m Hose
  • 1 x 61cm Hose
  • 1 x HP hose and TEK SPG

Apeks MTX-RC Single Cylinder Regulator Set

SKU: RC127000
    • Satin plated brass body with heat exchanging ribs for maximum thermal performance.
    • Break through, innovative over-moulded first-stage endcap and environmental diaphragm helps prevent ice build-up that can cause first stage free flow in extreme circumstances. Also protects the first stage from impact damage.
    • Ribbed diaphragm clamp for improved heat exchange in cold water conditions.
    • 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.
    • 5 x medium pressure ports, 4 mounted on a rotating turret for improved hose orientation
    • 2 x angled high pressure ports for optimal hose routing and fitting of transmitters.
    • Double swivel hose for greater freedom of movement and comfort.
    • Easy to grip DIN hand-wheel or over-moulded yoke hand-wheel, only requires one hand to release.
    • DIN, Yoke and M26 Thread available, 300bar, 232bar and M26 300bar (O2) respectively.
    • Tested for Octopus use - EN250A to 60 metres 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.
    • Protective bumpers to protect the second stage from impacts and scratches in the most vulnerable places.
    • Ergonomic and simple to use venturi lever.
    • Oversize breathing effort adjuster makes adjustment easy in cold water whilst wearing gloves.
    • Large purge button.
    • Reversible second stage for either a left or right hand gas supply configuration.
    • A heat exchanger (patented) dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water for a more comfortable breathe.
    • Features an innovative Diver Changeable Exhaust system (DCE). The system gives the diver the ability to change from a small exhaust tee to a large exhaust tee. The regulator is supplied with both sets of exhaust tees.
    • Comfo-bite mouthpiece
    • Flexible nylon braided hose, which has better cold water performance than traditional rubber hose.
    • Designed and manufactured in the UK.
    • No single-use plastic in the packaging
