Product Information
This package pairs the Apeks XTX50 Dive Regulator with the Apeks XTX50 Octopus, giving you a matched primary and backup air source built around the same over-balanced, diaphragm-design first stage technology. The XTX50 Regulator uses four medium-pressure ports on a rotating turret for clean hose routing, and its environmental dry system keeps water, silt, and contamination out of the main spring chamber, which also helps prevent ice buildup in cold conditions. You choose the connection type that fits your cylinder valve, DIN or Yoke, at checkout.
Both the regulator and octopus use a pneumatically-balanced second stage for smooth, easy breathing, along with braided flexi-hoses that are lighter, more flexible, and more durable than standard hoses, and rated for coldwater use. Each piece has a large, easy-to-operate purge button with a 2-stage progressive purge, so you can dial in a lower flow rate for tasks like filling a lift bag or hit the center for a full clearing purge. The XTX50 Regulator adds a Diver Changeable Exhaust system, letting you swap between a small exhaust tee to cut down bubble interference for photography and a large tee for a more compact, comfortable fit, and both sets come included.
The XTX50 Octopus includes a breathing effort control knob so you can desensitize the second stage while it's stowed and not in use, and its molded parts are treated with an additive that's active against MRSA, E-Coli, bacteria, fungi, viruses, mold, yeast, and algae. Both the regulator and octopus are compatible with EAN40 straight out of the box and share the same Comfo-bite mouthpiece. If you ever need to switch either piece from right-handed to left-handed hose routing, that conversion is quick for an Apeks Authorized Service Technician to perform.
- Over-balanced, diaphragm-design first stage on the XTX50 Regulator delivers superior performance as you descend
- Four medium-pressure ports on a rotating turret keep hose routing clean and eliminate sharp bends
- Environmental dry system keeps water, silt, and contamination out of the main spring chamber and helps prevent ice buildup
- Diver Changeable Exhaust system on the regulator includes both a small tee for reduced bubble interference and a large tee for comfort
- Pneumatically-balanced second stages on both the regulator and octopus deliver smooth, easy breathing
- Braided flexi-hoses on both pieces are lighter, more flexible, more durable, and rated for coldwater use
- Breathing effort control knob on the XTX50 Octopus lets you desensitize the second stage when it's stowed
- Molded parts on the octopus are treated with an additive active against MRSA, E-Coli, bacteria, fungi, viruses, mold, yeast, and algae
- Choose DIN or Yoke for the regulator's first stage so your primary and backup share one coherent, coldwater-rated setup

What are the key features of the Apeks XTX50 regulator?
The XTX50 uses Apeks' DST first stage with an over-balanced, environmentally sealed diaphragm design, giving 2 high-pressure and 4 medium-pressure ports mounted on a rotating turret for easy hose routing. The second stage is pneumatically balanced with a 2-stage progressive purge, an opening-effort control knob, and an integrated venturi lever, and it comes with both a small and large diver-changeable exhaust tee. It's rated for cold water below 10°C/50°F and is compatible with EAN40 nitrox straight out of the box.
What does the Apeks XTX50 regulator set include — yoke vs DIN, hose configuration?
The XTX50 first stage is available in both yoke and DIN configurations, with braided flexi-hoses and a chrome-over-marine-brass exterior. It ships in a right-handed hose configuration but can be converted to left-handed by an Apeks Authorized Service Technician, and an optional 5th port is available for sidemount or twin-cylinder setups. Both sizes of exhaust tee are included with the set.
What's the Apeks XTX50's second stage like?
The XTX50 second stage is pneumatically balanced for smooth, easy breathing, with an average work-of-breathing score of 0.70 joules/liter. It has large, easy-to-operate 2-stage progressive purge buttons, a soft-touch venturi lever, an opening-effort control knob, and a Comfo-bite mouthpiece.
How much does the Apeks XTX50 regulator weigh?
The Apeks XTX50 regulator weighs 1269g in the yoke configuration and 1139g in the DIN configuration.
What are the features of the Apeks XTX50 Octopus?
The XTX50 Octopus has a pneumatically balanced second stage with a breathing-effort control knob to desensitize it when stowed, a large 2-stage progressive purge button, and a silicone exhaust valve. It uses braided, cold-water-rated flexi-hoses, a Comfo-bite mouthpiece, and is EAN40-compatible out of the box; its molded parts are also treated with an antimicrobial additive. Like the primary XTX50, it can be converted from right- to left-handed by an Apeks Authorized Service Technician.
