Apeks MTX-R Sidemount Set Metric


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.


First Stage Available in yoke or DIN configuration. 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 forged 1st 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.

Second stages Simple to use with no dive controls, pre-settable cracking effort or venturi control by an Apeks approved qualified technician. High performance pneumatically balanced lever operated poppet valve. Large diver friendly self-flushing controllable purge button. Front cover with over-moulded elastomer bumpers incorporates a formed chrome plated brass plate improving durability of the demand valve. Large protective elastomer bumpers on the side and on the top to protect the demand valve from impacts and scratches in the most vulnerable places. Reversible second stage for either a left or right-hand gas supply. Hard wearing, satin chrome. All gas contact moulded parts are produced using an active protection additive that kills MRSA, protects against E-Coli, bacteria and fungi, and is also very effective against viruses, mold, yeast and algae. Large heat exchanger fitted to help reduce second stage freezing. Nitrox/Oxygen compatible
