The MTX-R sidemount set is a super tough, rugged, high performance, go anywhere sidemount regulator configuration designed to meet the rigours of cold water and extreme sidemount diving. The MTX-R is highly reliable and also very easy to service out in the field which make it an ideal choice for the expedition and exploration diver.

FEATURES & BENEFITS

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 and environmental diaphragm, a forged 1st stage body offering maximum thermal preference, a ribbed diaphragm clamp and a redesigned & enlarged heat exchanger on the 2nd stage with metal incorporated into the front cover design.

DETAILS

First Stage

Suitable for cold water use (below 10°C / 50°F)
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.
Over-moulded innovative endcap and environmental diaphragm, a forged1st stage body offering maximum thermal performance.
The 5th 3/8” UNF medium 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 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.

ADDITIONAL DETAILS

Second Stage

High performance, pneumatically balanced, lever operated poppet valve.
Large, diver friendly self-flushing controllable purge button.
Front cover with over-moulded elastomer incorporates a formed chrome plated brass plate improving durability of the second stage.
Large protective elastomer bumpers on the side and on the top to protect the second stage from impacts and scratches in the most vulnerable places.
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.
Comfo-bite mouthpiece
Double swivel hose
Flexible nylon braided hose has better cold water performance than traditional rubber hose.
