R4 TEC First Stage - EN250A

Ultra-compact balanced diaphragm regulator, ideal for cold water, stage/deco cylinders, and single cylinders.

The Tecline R4 TEC First Stage, available at DIR-STORE, is an incredibly compact regulator with top-level performance. Designed to withstand the most severe environmental conditions, it far exceeds the stringent safety requirements of the recent European standard EN250A for cold water diving. Its versatility makes it an excellent choice as a primary regulator for advanced recreational configurations, as well as the core of decompression systems.

Key Features and Benefits:

• Balanced Diaphragm Technology: Guarantees constant intermediate pressure and impeccable breathing parameters at any depth and with any residual cylinder pressure.
• Maximum Thermal Protection (Dry Chamber): Equipped as standard with a dry chamber isolated from the external environment and integrated with an additional cooling kit. This combination prevents water from coming into contact with the main spring, eliminating the risk of free-flow or freezing in icy waters.
• Military-Grade Materials: Entirely machined from marine bronze, a material that ensures optimal thermal conductivity and total resistance to salt corrosion and mechanical shocks.
• Rational Port Layout: Features 4 low-pressure (LP) ports and 2 high-pressure (HP) ports symmetrically arranged to allow for clean, hydrodynamic hose routing without forced bends.
  

Why buy the R4 TEC first stage?

• Perfect for Octopus Configuration: Thanks to its excellent airflow and the arrangement of the 4 LP ports, it is ideal for neatly and linearly managing both the primary second stage and the emergency second stage (octopus) on a single body.
• EN250A Certified Performance: Guarantees maximum safety and minimal breathing effort even in deep or challenging diving environments.
• Available in Dedicated O2 Version: For technical divers, the special R4 TEC O2 version is available with an M26x2 connection or with 25x2 threading, entirely degreased and factory assembled with materials compatible for safe use with 100% pure Oxygen.
