First Stage R2 TEC O2 M26x2 (EN250A)

The most versatile first stage in the Tecline range, in O2 version with M26x2 connection. Constructed from marine bronze with a balanced diaphragm, dry chamber, and 360° swivel turret, it offers extraordinary breathing performance well beyond the EN250A cold water requirements. Ideal for stage tanks, single tanks, twinsets, and sidemount configurations.

The Tecline R2 TEC O2 M26x2, available on DIR-STORE, is a technical first stage with extremely high operational flexibility, designed for the safe management of pure Oxygen and hyperoxic decompression mixtures.

Made of durable marine bronze, it utilizes a balanced diaphragm mechanism coupled with a dry chamber with an integrated cold water kit. This structure completely isolates the internal mechanisms from the aquatic environment, eliminating the risk of freezing and protecting the first stage from sediment and contaminants. The 360° swivel turret ensures ideal availability of low-pressure ports for clean hose routing, while the M26x2 thread ensures compliance with European regulations for Oxygen use.

Key Features:

• Natively O2 Compatible Version: Equipped with a DIN M26x2 connection (according to EN 144-3 standard) and specific materials suitable for use with pure Oxygen and hyperoxic Nitrox.
• 360° Swivel Turret: Flexible layout with 4 orientable LP ports (3/8" UNF) and 2 symmetrical HP ports (7/16" UNF), with the possibility of integrating an optional 5th axial LP port.
• Balanced Diaphragm & Dry Chamber: Ensures constant intermediate pressure at any depth and isolates internal components from freezing water and suspended particles.
• EN250A Cold Water Certification: Designed to operate in severe thermal conditions and at great depths, far exceeding the parameters required by the standard.
• Maximum Technical-Operational Versatility: The ideal first stage for stage tanks, but also extremely high-performing in single tank, twinset, and Sidemount configurations.
