Oxygen Set 100% R4WW + REC1 - DIN 26x2

Clean stage/decompression regulator set for Oxygen (100% O2) with DIN M26x2 connection (EN 144-3), equipped with R4 WW O2 diaphragm first stage with Cold Water (WW) system, REC1 second stage, LP hose, and transport bag.

The Tecline R4 WW REC1 100% O2 regulator set, available on DIR-STORE, is a high-performance decompression (stage set) configuration, certified (EN250A standard for water temperatures > 10°C) and designed for safe use with pure Oxygen and highly hyperoxic mixtures.

Unlike piston versions, the R4 WW first stage uses a balanced diaphragm mechanism with a swivel turret featuring dry chamber insulation (WW - Cold Water / Dry Chamber system). This technology prevents water ingress into the spring chamber, ensuring superior protection against freezing and sediment accumulation. The standardized DIN M26x2 connection prevents any connection errors with air-filled cylinders.

Main Features:

• R4 WW O2 Balanced Diaphragm First Stage: Constant airflow regardless of depth and cylinder pressure, equipped with a swivel turret for flexible hose routing around the decompression cylinder.
• WW System (Dry Chamber / Cold Water): Dry chamber isolated from the external environment, protecting internal components from ice, dirt, and mineral deposits.
• Standard M26x2 Connection (EN 144-3): Dedicated and mandatory threaded connection for safe use with pure Oxygen and hyperoxic Nitrox.
• EN250A Certification (> 10°C): Approved according to European safety parameters for diving in waters with temperatures above 10°C.
• Tecline REC1 O2 Second Stage: Compact and ergonomic profile, with smooth and balanced delivery designed for decompression stops.
• Flexible LP Hose (100 cm): Optimal length of 1 meter for convenient and tidy management of the second stage.
• Transport Bag Included: Supplied complete with a green Tecline protective case for safe storage of the equipment.
