Apeks MTX-RC Regulator Din – Sidemount / Twin Tank / Single
The MTX-RC combines a dry-sealed, over-balanced first stage with user-adjustable breathing controls. It suits divers who want a robust cold-water regulator platform and the ability to tune inhalation effort, with a rotating turret helping to keep hose routing organised.
Features and benefits
- Balanced gas delivery. The over-balanced diaphragm mechanism helps manage the supply to the second stage as diving conditions change.
- Adjustable breathing feel. The inhalation-effort control lets you tune the adjustable second stage within its operating range.
- Venturi control. Select the appropriate setting for surface handling or diving to help manage free-flow tendency.
- Environmental protection. The sealed first-stage chamber helps keep water and contaminants away from its working mechanism.
- Rotating hose turret. Arrange the low-pressure hoses around your preferred equipment layout.
- Comfortable mouthpiece hold. The Comfo-Bite palate bridge helps support the second stage without a hard bite.
Setup and compatibility
Connection: DIN. Choose the fitting that matches your cylinder valve and its pressure rating.

First Stage
- Breakthrough, innovative over-moulded first-stage endcap and environmental diaphragm helps to prevent ice build-up that can cause first stage free flow in extreme circumstances. Also protects the first Stage from impact damage.
- Ribbed diaphragm clamp for improved heat exchange in cold water conditions.
- 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.
- 5 x medium pressure ports, 4 mounted on a rotating turret for improved hose orientation
- 2 x angled high-pressure ports for optimal hose routing and fitting of transmitters.
- Double swivel hose for greater freedom of movement and comfort.
- DIN, Yoke and M26 Thread available, 300 bar, 232 bar and M26 300 bar (O2) respectively.
- Tested for Octopus use - EN250A to 60 m cold water.
