Oxygen Set 100% R4WW + TEC2 + SPG - DIN 26x2

Stage/Decompression regulator set complete with 52 mm metal pressure gauge, cleaned for Pure Oxygen (100% O2) with DIN M26x2 connection, R4 TEC WW O2 (wet chamber) balanced diaphragm first stage, TEC2 O2 balanced second stage, LP hose, short HP hose, and carry bag.

The Tecline R4 WW TEC2 100% O2 regulator set with SPG, available on DIR-STORE, represents the definitive and ready-to-use decompression configuration, designed for the technical diver who demands maximum regulator performance and full compliance with DIR standards.

What differentiates it from the standard version is the inclusion of the 52 mm technical diving pressure gauge with a metal casing and mineral glass, mounted on a short 20 cm rubber HP hose for immediate consumption monitoring without creating bulk. The system is driven by the R4 TEC WW O2 first stage (ultra-light 600 g balanced diaphragm with a wet chamber to prevent overbalancing) and the pneumatically balanced TEC2 O2 second stage with Venturi lever and inspiratory effort adjustment.

Main Features:

• 52 mm Metal Technical Pressure Gauge Included: Compact O2 SPG with ultra-resistant metal casing, mounted on a short 20 cm rubber HP hose for an extremely hydrodynamic stage cylinder layout.
• R4 TEC WW O2 First Stage (Wet Chamber): Compact and lightweight marine bronze (weight 600 g) balanced diaphragm structure. The absence of an environmental diaphragm eliminates the risk of gas overbalancing at high depths.
• Tecline TEC2 O2 Second Stage: High-performance pneumatically balanced design with external Venturi and inspiratory sensitivity adjustment for superior breathing comfort during decompression stops.
• Standard M26x2 Connection (EN 144-3): Standardized and exclusive DIN connection for maximum safety with pure Oxygen and hyperoxic Nitrox.
• DIR Routing and Profile: 100 cm Low Pressure hose designed for clean and linear hose management around the decompression cylinder, ideal for use with harness, backplate, and drysuit.
• Carry Bag Included: Original Tecline green protective case included in the kit for safe storage and transport.
