100% Oxygen Set R4WW + TEC2 - DIN 26x2

High-performance stage/decompression regulator set for Pure Oxygen (100% O2) with DIN M26x2 connection, featuring R4 TEC WW O2 (wet chamber) balanced diaphragm first stage, TEC2 O2 balanced second stage, 100 cm LP hose, and a carrying bag.

The Tecline R4 WW TEC2 100% O2 regulator set, available on DIR-STORE, is the ultimate solution for technical divers seeking excellence in decompression stops and perfect integration with DIR (Doing It Right) equipment and standards.

Designed for completely safe use with pure oxygen and hyperoxic Nitrox (EN250A certified for water temperatures > 10°C), this kit combines the R4 TEC WW O2 first stage (ultra-light 600 g balanced diaphragm with a wet chamber to prevent over-balancing at depth) with the TEC2 O2 second stage. The TEC2 offers pneumatically balanced delivery with Venturi and inspiratory effort adjustment, ensuring maximum breathing comfort. The 100 cm LP hose allows for clean and tidy routing on the stage cylinder.

Main Features:

• R4 TEC WW O2 First Stage (Wet Chamber): Ultra-light chrome-plated marine bronze structure (weight 600 g) with a balanced diaphragm. The absence of an environmental diaphragm eliminates the risk of gas over-balancing at high depths.
• Tecline TEC2 O2 Second Stage: Pneumatically balanced design with external Venturi and inspiratory sensitivity adjustment for top performance during decompression stops.
• Standard M26x2 Connection (EN 144-3): Standardized and exclusive DIN connection to prevent any connection errors with cylinders filled with air or other mixtures.
• DIR Configuration and Routing: 100 cm Low Pressure hose designed for hydrodynamic and essential routing on the stage cylinder.
• Carrying Bag Included: Original Tecline protective case in green for maximum safety during storage and travel.
