The Apeks XTX 50 DST Regulator is a perfect all-rounder regulator, perfectly suited for all types of diver. A Rotating Turret allows for perfect hose routing and less stress on your hoses because their mount can turn during use.

Who's the XTX50/DST For?

Environmentally Sealed, Over-Balanced and feature-rich the combination of the XTX50 and the DST 1st stage is great for any diver. Cold-Water Rated the DST works well both in warm and cold waters and the flexibility of the swivel turret mean that you can use the 1st stage on single, twin and stage cylinders as needed.

Compatible With

All Low-Pressure Ports are 3/8" so any of these LP hoses will fit.

Either the XTX40 or upgrade to the XTX50 Octos are made to work with the DST but some assembly, testing and adjustment may be required.

DST 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 rate faster than ambient. This results in superior performance at depth.
  • 2 HP ports and 4 MP ports on a rotating turret are angled for optimum hose routing
  • An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out.

XTX50 Second Stage

  • Pneumatically-balanced second stage results in smooth, easy breathing.
  • The XTX purge buttons are large and easy to operate. A 2-stage progressive purge is used - press the purge on the side for a lower flow rate, useful where more control is required such as filling lift bags etc, then press in the centre for the full effect of the purge, i.e. when regulator clearing etc.
  • The large venturi lever has a soft touch rubber grip, which makes it easier to locate and use. The lever reduces the amount of grit ingress and therefore resists any possible friction giving a smooth operation.
  • Easy-to-grip opening effort control knob keeps the diver in control.
  • The second stage is manufactured with active protection against infection as all moulded parts are produced with an additive that kills MRSA, protects against E-Coli, bacteria and fungi, and is also very effective against viruses, mould, yeast and algae.
  • A silicone exhaust valve improves the breathing performance of the regulator.
  • The Comfo-bite™ mouthpiece virtually eliminates jaw-fatigue.
  • 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.
