Apeks XTX50/40 Regulator


The XTX50/40 is pure bulletproof awesomeness from the UK.

** Assembled and Tested by our on-site Servicing Technicians before sending **

You may only be diving to 18m or even 30m, but don't you want peace of mind that the regulator keeping you alive is regularly dived to over 60m by some of the best divers in the world?

Imagine owning a regulator that can last you 30 years, well this is one of the few regulators on the market that you can.  As part of the part of the Aqualung famiily, which has the US Diver Conshelf regulator in its family tree.  And still see US Diver regulators from the 70's and 80's in use.

This popular 1st stage regulator has four medium-pressure ports all mounted on a rotating turret. This results in optimal hose routing while eliminating sharp bends in the hose. 

There is the optional 5th port which is useful in twins and side mount.  To add the 5th port, the HP seat will be disturbed and so can only be done along with a service.  So if you are thinking you would like the 5th port, then let us know so we can get in a pre-assembled 1st stage with 5th port ready for you to use straight out of the box.  

It is environmentally sealed, meaning it is a great cold water regulator.  Suitable for coldwater use (below 10 C / 50 F).

The Second stage features an innovative Diver Changeable Exhaust system (DCE). This system gives the diver the ability to change from a small exhaust tee to a large exhaust tee. This gives the user a choice, wider exhaust tee for minimal bubble interference (essential for underwater photography) and narrow exhaust tee for a smaller compact comfortable regulator. The regulator will be supplied with both sets of exhaust tees.

Can be converted from a right-handed hose configuration to a left-handed one. The process of changing the regulator to a left-handed configuration is both quick and simple. However this procedure MUST only be performed by an APEKS Authorized Service Technician.

When you order simply choose between YOKE (screw on over the tank valve) or DIN (screw into the tank valve) configurations.  We have also included an option to upgrade to add an SPG onto the regulator set.

Braided flexi-hoses are now standard on all models. These hoses are lighter weight, more flexible and more durable.

Compatible with EAN40 out of the box.

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 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.  Our servicing technician raves about Environmentally Sealed systems all the time.

Second Stage:

  • Pneumatically-balanced second stage results in smooth, easy breathing regulator
  • 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 center 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 2nd stage is manufactured with active protection against infection as all molded 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

Comes with full manufacturers warranty and free shipping anywhere in New Zealand.  As we back all of our products, if you are not satisfied, for ANY reason, then simply return the regulator for a full refund.

We'll assemble and test the regulator onsite so it's ready for you to use straight out of the box.

I've used this for years

This is my favorite regulator. I've used this regulator for around 8 years and absolutely love them. Easy to breathe, comfortable and they still look in great condition. Would highly recommend this for anyone looking to get a new reg set.
