Oxygen Set 100% R4 + REC1 + SPG - DIN 26x2

Stage/decompression regulator set complete with O2 gauge, cleaned for Pure Oxygen (100% O2) with DIN M26x2 connection, R4 O2 balanced diaphragm first stage with built-in anti-freeze system, REC1 second stage, LP hose, short HP hose, and carrying bag.

The Tecline R4 REC1 100% O2 regulator set with SPG, available on DIR-STORE, is a ready-to-use decompression configuration (stage set) designed for divers seeking maximum thermal reliability and constant gas supply control.

What differentiates it from the standard version is the inclusion of the compact Tecline O2 pressure gauge, mounted on a short 20 cm rubber HP hose for immediate cylinder pressure readings without compromising the hydrodynamic nature of the equipment. The balanced diaphragm R4 O2 first stage incorporates an integrated anti-freeze system that prevents ice formation even in cold waters or during prolonged air delivery flows. The kit is completed by the compact REC1 O2 second stage and a 100 cm LP hose for clean routing.

Key Features:

• Dedicated O2 Pressure Gauge Included: Equipped with Tecline O2 SPG (300 bar scale, 200 bar working pressure) mounted on a short 20 cm rubber HP hose for continuous and rational gas consumption monitoring.
• Integrated Anti-freeze System: Thermal protection incorporated into the R4 O2 first stage to ensure safety and efficiency even in cold water dives.
• R4 O2 Balanced Diaphragm First Stage: Ensures a constant and high-performing airflow at any depth and residual cylinder pressure.
• Tecline REC1 O2 Second Stage: Compact and ergonomic profile, designed to reduce breathing effort and eliminate jaw fatigue during decompression stops.
• Standard M26x2 Connection (EN 144-3): Specific mandatory threading to prevent incorrect connections with air-filled cylinders.
• Flexible LP Hose (100 cm): Optimal 1-meter length for perfect routing of the second stage around the decompression cylinder.
• Carrying Bag Included: Original green Tecline protective case included in the package.
