First Stage R4 TEC O2 M26x2 (EN250A)

Compact balanced diaphragm first stage in O2 version with M26x2 connection, ideal for use with pure Oxygen and hyperoxic decompression mixtures. EN250A certified for cold water, it features a dry chamber, additional cold water kit, and a high-strength marine bronze body. Perfect for stage tanks.

The Tecline R4 TEC O2 M26x2, available on DIR-STORE, is an ultra-compact technical first stage designed specifically for safe management of Oxygen and decompression mixtures.

Constructed from marine bronze, it combines a reduced footprint with extraordinary breathing performance that far exceeds the stringent requirements of the European standard EN250A for cold water diving. The balanced diaphragm system, combined with the dry chamber and integrated cold water kit, completely isolates the internal mechanics from the external environment, preventing freezing and protecting the regulator from sediments and hydrocarbons. The DIN connection with M26x2 threading ensures full compliance with European regulations for Oxygen use.

Key Features:

• Native O2 Compatible Version: Equipped with a DIN M26x2 connection (according to EN 144-3 standard) and materials/lubricants suitable for use with Oxygen and high-percentage Nitrox.
• 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 extreme thermal conditions while maintaining very low breathing effort.
• Optimized Port Layout: Features 4 LP ports (3/8" UNF) and 2 HP ports (7/16" UNF) positioned to allow for clean hose routing, especially on stage tanks.
• Maximum Versatility of Use: Although it is an excellent choice for decompression/stage tanks, its compactness also makes it great for single tanks or double tanks.
