First Stage R2 TEC - EN250A

Ultra-versatile balanced diaphragm regulator with 360° swivel turret, dry chamber, and maximum configuration flexibility.

The Tecline R2 TEC First Stage, available on DIR-STORE, is by far the most versatile and flexible model in the entire Tecline regulator range. Designed with a 360° swivel turret and meticulously planned port arrangement, it is the preferred choice for technical divers seeking exceptional performance and flawless hose routing in any configuration: from sidemount to twin-set, and even stage/deco cylinders. It largely exceeds the most stringent safety requirements of the latest European standard EN250A for cold water diving.

Key Features and Benefits:

• 360-Degree Swivel Turret: Allows for free and fluid orientation of the low-pressure hoses, drastically reducing tension on the diver's neck and mouth. This is a fundamental element for optimizing hose routing in complex configurations.
• Balanced Diaphragm Technology: Ensures constant intermediate pressure and incredibly smooth air delivery, regardless of depth and residual cylinder pressure.
• Total Thermal Insulation (Dry Chamber): Equipped with a sealed dry chamber and an additional cooling kit that keeps internal mechanisms protected from direct contact with cold water and sediment, eliminating the risk of freezing (free-flow) in extreme environments.
• Marine Bronze Construction: The body is entirely made from marine-grade bronze to ensure absolute structural robustness, excellent thermal conductivity, and total corrosion resistance.
• Up to 5 Low-Pressure Ports: Features 2 high-pressure (HP) and 4 standard low-pressure (LP) ports, with the optional possibility of adding a fifth axial LP port on the turret head to further optimize routing.

Why buy the R2 TEC first stage?

• The undisputed king of Sidemount and Stages: Thanks to the swivel turret, it allows hoses to run parallel to the cylinder body, ensuring a hydrodynamic, clean, and kink-free configuration.
• One regulator for a thousand uses: Whether you decide to use it on a recreational single cylinder, a technical twin-set, or decompression cylinders, the R2 TEC adapts perfectly and always offers maximum performance.
• Available in Dedicated O2 Version: For technical divers, the special R2 TEC O2 version is available with an M26x2 or 25x2 threaded connection, entirely degreased and factory-assembled with specific materials for safe use with 100% pure Oxygen.
