Apeks TEK3 Set

Apeks TEK3 Set is a streamlined twinset regulator set designed to keep hose routing tidy, reduce snag risk, and make manifold valves easier to reach. This regulator set combines dedicated 1st stages with matching 2nd stages for technical diving, where reliable breathing performance and clean equipment configuration matter. It suits twin cylinder setups especially well, while also working for single cylinder or stage cylinder use when a compact, no-kink hose layout is preferred. Built for cold-water use, it uses an environmentally sealed design to help keep the internal spring chamber protected from water, silt, and contamination.

• Twinset-focused regulator set built for clean, downward hose routing and reduced snagging in technical diving
• Purpose-made 1st stages for twin cylinders to improve access to manifold valves and help prevent hose kinking
• Over-balanced diaphragm 1st stage design that increases medium pressure faster than ambient pressure as depth increases
• Port layout designed for tidy routing with 1 HP port and 3 MP ports angled downward on each 1st stage
• Environmentally sealed dry chamber helps reduce freezing risk and keeps debris out of the 1st stage spring chamber
• Maximum working pressure 300 bar (4350 psi)
• Pneumatically balanced 2nd stage for smooth breathing with adjustable control via the Inhalation Effort Adjustment Knob
• Two-stage progressive purge with separate low-flow and full-flow operation for better control during tasks like lift bag filling
• Venturi lever with a soft-touch rubber grip, designed to be easy to find and use while helping limit freeflow at the surface
• Silicone exhaust valve and heat exchanger around the valve mechanism to support breathing performance in colder conditions
• Comfobite mouthpiece designed to reduce jaw fatigue during longer dives
• Trivalent chrome plating described by the manufacturer as using less energy than traditional chrome
