Go warm, go cold, go deep, go anywhere. Enjoy control in the extreme with the MTX-RC scuba diving regulator. Combining rugged, military grade engineering with the super-smooth breathing experience that Apeks regulators are renowned for, the MTX-RC is the regulator that lets you explore more.
Featuring the same freeze-resistant technology enjoyed by the whole MTX-R range, the MTX-RC resists free-flows in even the coldest temperatures, while offering the user the additional flexibility to adjust the settings for a more 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.
Includes a tactical style messenger bag to keep your regulators safe on your travels. Perfectly sized for a laptop, it’s also your new work bag!
First Stage
- 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.
2nd Stage
- 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

Free Parts for Life Program (Regulator Service Agreement)
The Free Parts for Life Program allows the customer to receive free parts when the regulator is due for overhaul. Free parts consist of the normal replacement items as found in the Regulator 1st & 2nd Stage Service Kits. Labor charges are not covered. Assuming the program guidelines are followed, the Free Parts for Life Program will apply to the life of the regulator and will significantly reduce the cost of ownership. This program is in addition to the standard product warranties outlined in the owner’s manual.
The Free Parts for Life Program is a commitment by you (the Regulator owner), your Aqua Lung Dealer and Aqua Lung. To participate, you must be the original owner and have purchased the regulator from an Authorized Aqua Lung or Apeks America Dealer. Rainbow Reef Dive Center is an authorized Aqualung Dealer. We can service and repair Aqua Lung and Apeks equipment. The regulator must be brought to an Authorized Dealer at least once a year for inspection or overhaul according to the below schedule:
Register Your Aqualung Regulator Here
- Year #1: Inspection
- Year #2: Overhaul
- Year #3: Inspection
- Year #4: Overhaul
- Year #5: Etc.
To keep the Free Parts for Life Program active, both inspections and overhauls need to be documented in the Annual Service & Inspection Records included in the Owner’s Manual CD or can be found online here. If an inspection or overhaul is missed, the regulator no longer qualifies for the Free Parts for Life program.
