Product description Apeks MTX-R DIN

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 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.


- 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
- Break through, innovative over-moulded 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-moulded yoke hand-wheel, only requires one hand to release
- DIN, Yoke and M26 Thread available, 300bar, 232bar and M26 300bar (O2) respectively

- 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

- 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 lock out feature for retaining second stage in the mouth of an unconscious diver during rescue and to assist with jaw fatigue
