MTX-R First Stage

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.

First Stage

  • 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.
  • 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.
  • DIN, Yoke and M26 Thread available, 300 bar, 232 bar and M26 300 bar (O2) respectively.
  • 5 x 3 / 8″ UNF (Unified National Fine) medium pressure ports
  • 2 x 7 / 16″ UNF high pressure ports.
  • 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).
