Apeks MTX-RC 1st Stage

The MTX-RC first stage has been designed to provide optimum cold water performance from it’s satin plated brass body with heat exchanging ribs, to the innovative over-moulded first stage endcap and environmental diaphragm. It helps to prevent ice build-up that can cause free-flowing of a first stage in extreme weather circumstances. These features also protect the first stage from impact damage. The diaphragm design provides an over-balancing feature. This allows the medium pressure gas in the hose to increase at a faster rate than ambient, resulting in superior performance at depth.

The first stage has 5x medium pressure ports (4 of which are mounted on a rotating turret for improved hose orientation), and 2 angled high pressure ports. These ports allow for optimal hose routing and fitting of air pressure transmitters. It has a double swivel hose for greater freedom of movement and comfort while diving, and an easy to grip DIN hand-wheel, or over-moulded yoke hand-wheel which require only one hand to release. Tested for Octopus use – EN250A to 60 metres cold water.
