Oxygen Set 100% R4 + TEC1 - DIN 26x2

Stage/decompression regulator set for Pure Oxygen (100% O2) with DIN M26x2 connection, featuring an R4 TEC O2 diaphragm first stage with integrated anti-freeze system, a high-flow TEC1 O2 second stage, a 100 cm LP hose, and a carrying bag.

The Tecline R4 TEC TEC1 100% O2 regulator set, available at DIR-STORE, is a superior technical decompression configuration (stage set), designed to ensure reliability, thermal safety, and breathing comfort during stops with pure Oxygen or highly hyperoxic mixtures (EN250A certified).

The combination of the balanced diaphragm R4 TEC O2 first stage — characterized by a compact body with fixed ports and an integrated anti-freeze system to prevent ice formation in demanding dives — and the TEC1 O2 second stage (equipped with a lever for Venturi effect adjustment) offers smooth and consistent delivery. The flexible 100 cm hose ensures a clean and hydrodynamic trim around the stage cylinder.

Key Features:

• Integrated Anti-freeze System: Thermal protection incorporated into the R4 TEC O2 first stage to prevent freezing during prolonged decompression stops or in cold water.
• Tecline R4 TEC O2 First Stage: Compact and robust balanced diaphragm mechanism, without a swivel turret for maximum essentiality and with oxygen-cleaned and dedicated O2 ports.
• Tecline TEC1 O2 Second Stage: Smooth, high-flow delivery with a Venturi adjustment lever, ideal for reducing inhalation effort during stationary stops.
• Standard M26x2 Connection (EN 144-3): Standardized and exclusive threaded connection for maximum safety with pure Oxygen and hyperoxic Nitrox.
• EN250A Certification: Complies with European safety standards for diving regulators.
• Flexible LP Hose (100 cm): Optimal 1-meter length for perfect routing of the second stage.
• Carrying Bag Included: Original green Tecline protective case for safe storage of equipment.
