The MTX-R is based on the MTX military regulator and is a super tough, rugged, high performance, go anywhere regulator. The MTX-R has excellent cold-water performance and has a greatly reduced risk of free flow. This has been achieved by improving several areas, including an innovative endcap solution that solves a long-challenged reality for cold-water divers of the first stage freeze up.
This regulator is designed to meet all aspects of the NEDU (Navy Experimental Dive Unit) military requirements for diving in very cold water. The MTX-R is highly reliable and also very easy to service out in the field.
Features & Benefits
- 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
- Compact environmentally dry sealed diaphragm system completely eliminating the maintenance issues associated with silicone, oil or grease filling
- Breakthrough, innovative over-molded first-stage endcap & 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
- Easy to grip DIN hand-wheel or over-molded yoke hand-wheel, only requires one hand to release
- DIN, Yoke and M26 Thread available, 300bar, 232bar and M26 300bar (O2) respectively
- 5 x 3/8” UNF (Unified National Fine) medium pressure ports
- 2 x 7/16” UNF high-pressure ports
- The 5th 3/8” UNFmedium 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 to 60 meters 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
- Simple to use with no dive adjustment controls and reduced chance of free flow occurrence, pre-settable cracking effort or venturi control by an Apeksapproved qualified technician

- The 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
- Removable bungee necklace with a lockout feature for retaining the second stage in the mouth of an unconscious diver during rescue and to assist with jaw fatigue

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.
