Product Description

Apeks XTX20 Stage 4 Set

This regulator has the performance of the XTX40, without the cold water features, it is well suited for warm water conditions and the price makes it an exceptional value.


Designed for water above 50º F (10º C)

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. Only the compact exhaust tee is supplied.

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.

Available in yoke or din configuration

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:

– A balanced, diaphragm design provides consistent easy breathing from start of dive until end.
– 1 HP port and 4 MP ports are angled for optimum hose routing

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 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.
– 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

Console 2-Gauge – SPG/SDG:

The console clearly displays your pressure and depth readings for easy viewing under water and the dials have a long phosphorescent effect for better reading in poor visibility conditions.

– The gauge case is made from nickel plated brass
– The dial window is made of highly shock resistant material (anti-splinter polycarbonate)
– A specially designed housing protects the gauge and HP hose fitting from accidental damage
– A large loop area designed into the housing allows for easy attachment.
– There is an over-pressure capsule fitted in the back of the module to prevent the screen from exploding in the unlikely event of the internal mechanism failing.
– Dials have a long phosphorescent effect for better reading in poor visibility conditions
– There are 2 attachment areas integrated into the design for position flexibility
