Apeks XTX50 Yoke Regulator with XTX40 Octopus Package
By Apeks Marine Equipment | Yoke (A-Clamp) Connection | Over-Balanced Cold-Water Design | Swivel Turret First Stage
Dive with absolute confidence in extreme environments with the Apeks XTX50 Yoke Regulator and XTX40 Octopus Package. Featuring a standard Yoke (A-Clamp) first stage connection, this benchmark cold-water setup attaches quickly to standard scuba valves worldwide while delivering ultra-smooth air breathing at any depth or water temperature.
The package pairs the fully adjustable XTX50 primary second stage with the rugged, high-flow XTX40 yellow octopus second stage. Powered by an over-balanced DST Yoke first stage featuring a rotating swivel turret, this set offers clean, stress-free hose routing for all recreational and cold-water diving configurations.
Over-Balanced 1st Stage & Environmental Dry Seal
Apeks' over-balancing technology allows medium-pressure gas in the hose to increase faster than ambient depth pressure, resulting in effortless breathing at deep depths. An environmentally dry sealed chamber protects internal working components from water, salt, and silt while virtually eliminating freeze-up risks in near-freezing water.
Key Features & Performance Highlights
- Standard Yoke (A-Clamp) Fitting: Fits standard 232 bar Yoke cylinder valves for universal compatibility across dive centers and rental tanks worldwide.
- Adjustable Primary Cracking Effort: The XTX50 second stage features an external breathing resistance adjustment knob to fine-tune air delivery for depth, current, or personal preference.
- Rotating Swivel Turret First Stage: Features 4 low-pressure (LP) ports on a rotating turret and 2 high-pressure (HP) ports for optimal hose routing.
- Reversible Venturi System: Both 2nd stages feature a reversible Venturi lever (pre-dive / dive switch) to prevent surface free-flows and optimize airflow underwater.
- High-Visibility XTX40 Octopus: Matching pneumatically balanced secondary 2nd stage with a bright yellow purge cover and high-flex yellow octopus hose.
- Comfo-Bite Mouthpieces: Reduces jaw fatigue on long dives using Apeks' comfortable silicone mouthpiece bridge.
