Stage Regulator Set – R4WW 1st Stage + TEC2 2nd Stage + Pressure Gauge

The high-performance combination that unites the lightness of the R4 TEC WW wet-chamber first stage with the avant-garde fluid dynamics of the balanced TEC2 second stage. Ideal for travel, rebreather systems, stage tanks, and advanced recreational use in warm or temperate waters (> 10°C). Configure the type of LP hose and select the size and material of the HP hose from the dropdown menu.

The Tecline R4 WW TEC2 + SPG Set, available on DIR-STORE, is the perfect choice for those seeking maximum breathing comfort combined with an extremely lightweight and hydrodynamic profile.

The system is powered by the R4 TEC WW (Warm Water) balanced diaphragm first stage, which, at just 590 grams, eliminates the superfluous weight of dry chambers, offering a constant and massive airflow. In this set, it is paired with the top-of-the-range balanced TEC2 Black second stage, equipped with a DFS (Direct Flow System) and a heat exchanger to ensure extraordinarily smooth and natural delivery in all conditions.

Main Features of the Set:

R4 TEC WW First Stage (Specific for Travel and Stage):

• Wet Chamber Balanced Diaphragm: Designed for waters above 10°C. Ensures a direct mechanical response and constant performance at any depth, regardless of the residual pressure in the tank.
• Record Lightness (590 g): Made of chrome-plated marine bronze with 4 LP ports and 2 HP ports (DIN 300 bar connection). Drastically lightens the weight of airline baggage and in-water configuration.

TEC2 Black Second Stage (Unparalleled Breathing Comfort):

• Pneumatic Balancing & DFS System: Optimizes the dynamics of internal flows within the casing, minimizing inhalation effort.
• Dual Control During Dive: Equipped with a knob for micrometric adjustment of the initial inhalation effort and a lever for managing the Venturi effect (essential to prevent free-flow when positioned as a backup or attached to a stage).
• Reversible and Ergonomic Casing: Impact-resistant technopolymer structure, reversible on both sides for maximum routing customization.

SPG 52 mm Technical Pressure Gauge: Precision analog instrument with a metal casing and a highly visible 52 mm dial for quick and safe gas monitoring.

🛒 Customization: Configure the set according to your needs from the dropdown menu:

• LP Regulator Hose: Fixed length at 100 cm. Choose between the classic Rubber hose or the flexible Proflex (supplied as standard in black Proflex version).
