Regulator Set – R4WW 1st Stage + TEC1 2nd Stage

Balanced diaphragm regulator group with wet chamber and adjustable second stage, ultra-compact and ideal for travel, stage cylinders, rebreathers, and warm water configurations.

The Tecline R4WW TEC1 Regulator Set, available at DIR-STORE, is a high-performance system specifically designed to offer maximum reliability and lightness for diving in waters above 10°C. Utilizing a wet chamber diaphragm first stage (WW - Warm Water), this kit eliminates the external environmental diaphragm, thereby eliminating the risk of imbalance or flow drops at maximum depths. Paired with the high-performance adjustable TEC1 second stage, it represents an excellent choice for powering stage/deco cylinders, rebreather systems, or travel-oriented single and twin cylinder configurations.

Technical Features:

• First Stage R4 TEC WW (Wet Chamber and Anti-Imbalance): Made of forged marine bronze with heavy chrome plating, weighing just 590 grams. The wet chamber design optimizes heat exchange in temperate and warm waters, while the internal architecture protects the regulator from extreme ambient pressure variations, ensuring constant delivery at any depth. It has 4 LP ports and 2 fixed HP ports.
• Second Stage TEC1 (Universal and Balanced): A pneumatically balanced regulator with a classic, compact, and ultra-reliable design (250 g). It drastically reduces breathing effort by adapting to cylinder pressure variations, while the aluminum front ring shields the casing from accidental impacts.
• Total Flow Control and Heat Exchanger: Although the first stage is optimized for waters above 10°C, the second stage integrates an auxiliary heat exchanger on the hose connection. The diver can calibrate the delivery in real-time thanks to the micrometric breathing resistance knob and the Venturi effect adjustment lever (anti-free-flow).
• Optimal Loading Geometries: Thanks to the linear arrangement of the first stage outlets, this set is perfect for clean oxygen or diluent supply in rebreathers and for setting up stage cylinders (while it is not recommended for pure Sidemount layouts).
• Custom Hose Choice: The set includes the original Tecline regulator bag and allows for complete customization of the low-pressure hose layout, selecting the millimeter length and preferred compound (Traditional heavy black rubber or flexible Proflex Tecline braided hose).
