100% O2 Set R4 + TEC2 + SPG - DIN 26x2

Stage/decompression regulator set complete with O2 gauge, cleaned for Pure Oxygen (100% O2) with DIN M26x2 connection, R4 O2 diaphragm first stage with integrated antifreeze, TEC2 O2 Green pneumatically balanced second stage, LP hose, short HP hose, and carrying bag.

The Tecline R4 TEC2 100% O2 regulator set with SPG, available at DIR-STORE, represents a complete and ready-to-use solution for managing decompression stops with pure Oxygen or highly hyperoxic mixtures, combining maximum breathing performance with continuous gas supply monitoring.

In this version, in addition to the R4 O2 balanced diaphragm first stage (with built-in anti-freeze system) and the TEC2 O2 Green second stage (pneumatically balanced, 260g weight, DFS system, Teflon coating, and additional heat exchanger), the compact Tecline O2 gauge is included. Mounted on a 15/20 cm rubber HP hose, it ensures immediate and precise reading of residual pressure with minimal hydrodynamic bulk.

Key Features:

• Dedicated O2 Pressure Gauge Included: Equipped with Tecline O2 SPG (300 bar scale, 200 bar working pressure) mounted on a short rubber HP hose (15/20 cm) for clean and hydrodynamic management.
• R4 O2 Diaphragm First Stage with Antifreeze: Balanced O2-cleaned diaphragm mechanism, featuring built-in thermal anti-freeze protection to prevent ice buildup in cold water.
• Tecline TEC2 O2 Green Second Stage: Pneumatically balanced design with DFS (Direct Flow System), stainless steel outer ring, and high thermal, mechanical, and chemical resistance body.
• Advanced Anti-Ice Technology: Metal components of the second stage coated with Teflon against freezing and an additional heat exchanger for cold water.
• Dual Customizable Adjustment: Knob for inspiratory resistance adjustment and Venturi lever, for performance exceeding EN250A standard requirements.
• Standard M26x2 Connection (EN 144-3): Standardized and exclusive thread for maximum safety with pure Oxygen and hyperoxic Nitrox.
• Flexible LP Hose (100 cm): Optimal 1-meter length for perfect routing of the second stage around the decompression cylinder.
• Carrying Bag Included: Original Tecline green protective case for safe storage and transport.
