Oxygen Set 100% R4WW + TEC1 - DIN 26x2

Lightweight and compact stage/decompression regulator set for Pure Oxygen (100% O2) with DIN M26x2 connection, featuring an R4 TEC WW O2 diaphragm first stage (wet chamber), a very high breathability TEC1 O2 second stage, an LP hose, and a carrying bag.

The Tecline R4 WW TEC1 100% O2 regulator set, available on DIR-STORE, is an ultra-compact and versatile decompression configuration (stage set), EN250A approved for water temperatures above 10°C (> 10°C). Designed specifically for safe use with pure Oxygen and hyperoxic mixtures, it is the ideal choice for both stage cylinders and Rebreather gas supply during travel.

The R4 TEC WW O2 first stage, made of chrome-plated marine bronze weighing only 600 grams, utilizes a balanced diaphragm mechanism with a wet chamber. The absence of an external environmental diaphragm prevents the "over-balancing" phenomenon (gas cut-off/blockage at high depths). In combination with the TEC1 O2 second stage, equipped with a Venturi lever, it guarantees smooth delivery and excellent performance with minimal bulk.

Main Features:

• Compact and Lightweight R4 TEC WW O2 First Stage: Ultra-lightweight construction in chrome-plated marine bronze (only 600 g), ideal for the traveling technical diver and for Rebreather configurations or stage cylinders.
• Balanced Diaphragm with Wet Chamber: Ensures constant airflow and prevents gas over-balancing at high depths.
• Optimized Turret and Ports: Equipped with 4 Low Pressure (LP) ports and 2 High Pressure (HP) ports for versatile hose routing.
• Tecline TEC1 O2 Second Stage: High-flow second stage with a lever for Venturi effect adjustment, to minimize inhalation effort during decompression stops.
• Standard M26x2 Connection (EN 144-3): Standardized and exclusive threaded connection for safe use with pure Oxygen and hyperoxic Nitrox up to 300 bar.
• Flexible LP Hose (100 cm): 1-meter length for perfect routing of the second stage around the cylinder.
• Carrying Bag Included: Original Tecline protective bag in green included in the package.
