The XTX100 Single Cylinder Set is designed to be used in a long hose style single cylinder equipment configuration.

The XTX100 Single Cylinder Set is useful in situations where the large gas volumes of a twin cylinder configuration are not required. The package includes 2 x XTX 100 Primary 2nd stages, 1 x XTX 100 1st stage, 2.1m Hose, 61cm Hose (both double swivel hoses), a HP hose and TEK SPG.

First Stage:

  • Uses the FST type first stage.
  • Satin finish.
  • 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 are angled for optimum hose routing.
  • An environmental dry system keeps water out of the main spring chamber thus preventing ice build-up and keeping silt and contamination out.

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, then press in the centre for the full effect of the purge.
  • Reversible second stage for either a left or right hand gas supply configuration.
  • 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.
  • 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



  • Features an innovative Diver Changeable Exhaust system (DCE). The system gives the diver the ability to change from a small exhaust tee to a large exhaust tee. The regulator is supplied with both sets of exhaust tees.
  • An optional 5th port is available which features the additional bonus of an integrated heat exchanger (available on the Tungsten, XTX200 and XTX100 first stages only).
  • The same basic equipment platform is used when diving a single cylinder recreational configuration on a shallow reef or a twin cylinder technical diving configuration on a wreck or in a cave.
  • Easy to expand the system to a twin cylinder setup when required (just requires one more 1st stage)
  • Double swivel hose for greater freedom of movement and comfort.
  • Reversible second stage for either a left or right hand gas supply configuration.
  • Suitable for coldwater use (below 10 C / 50 F).
  • This set comes with 2 x XTX100 second stages one on a 210cm (83”) hose and the other on an 61 (24”) hose.
  • Included in the box is an Apeks TEK Gauge in chromed brass.

Should you wish to later move to twinset diving, you'd simply need to purchase an additional XTX100 first stage to convert this set for twinset use.
