Apeks XTX 50 Regulator - DS4 DIN

Availability: In stock


Quick description:

The XTX50/DS4 DIN gives the same performance as the XTX50 just with a different first stage.

The DS4 lacks the rotating turret and has only one HP port. This compact first stage has stood the test of time and is a favourite among technical divers.

The XTX50/DS4 qualifies for free parts for life.

The XTX50 is for the discriminating diver who wants the benefits of a feature-rich regulator at a moderate price.

  • Available in either DIN or Yoke configurations
  • Compatible to EAN 40 right out of the box
  • Optional DIN to Yoke converter and Free Flow Control device, which can isolate a free-flowing 2nd stage


All medium pressure ports are now 3/8°” so that the reversible XTX second stage can mount to either side of the first stage.

The over-balancing feature allows the medium pressure air in the hose to increase at a rate faster than ambient pressure resulting in superior performance.

Environmental Dry Sealing system

New XTX pneumatically balanced second stage has left/right reversibility and a Diver Changeable Exhaust (DCE) system. This system gives the diver the ability to change from a large exhaust tee to a smaller exhaust tee. The large tee provides the best exhaust bubble dispersion; the smaller tee is lighter weight and compact. Both exhaust tees are included with the regulator.

Improved exhalation performance and overall work of breathing

This pneumatically balanced second stage has diver-adjustable controls for opening effort and venturi control

Suitable for cold-water use

Indexable, tactile and audible venturi adjustment
