The XTX50 is for the discriminating diver who wants the benefits of a feature-rich regulator at a moderate price. This popular 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. The XTX40 Octopus provides the same features and performance as the XTX40 second stage and includes left / right hand reversibility. It comes with a high visibility yellow front cover and a 36” yellow hose. Suitable for cold water use (below 10 C / 50 F). This product qualifies for Free Parts for Life 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 Optional 5th port is available for sidemount or twin cylinder set ups. 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 Suitable for coldwater use 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 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. 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 Connections Yoke and DIN available Type of first stage Over-balanced diaphragm design, environmentally sealed Body Type MP ports mounted on swivel turret Number of HP ports 2 (7/16" UNF) Number of MP ports 4 with 5th port option (3/8" UNF) Environmental Dry Kit Standard First stage exterior Chrome over marine brass Orientation Convertible LH or RH Coldwater Use Yes Type of second stage Pneumatically balanced Opening Effort Control Knob Yes Integrated Venturi Lever Yes Mouthpiece Comfo-bite™ Exhaust tee Diver Changeable - comes with 2 sets Heat Exchanger for freezing resistance Yes Hose type Braided Flexi-hose Overall work of breathing (WOB) scores Avg. 0.70 joules/liter Nitrox compatible Yes to 40% O2 when new, out of the box / Can be cleaned to 100% Weight Yoke 1269g / DIN 1139g
