DIR Regulator Set – 1st Stage R2 + 2nd Stage TEC1 + Pressure Gauge

Complete twinset configuration compliant with DIR standards, featuring two diaphragm first stages with five axial low-pressure ports, adjustable second stages, a metal technical pressure gauge, and an accessory kit.

The Tecline R2 TEC1 + SPG DIR Set Regulator Kit, available at DIR-STORE, is the ultimate all-in-one technical package for twinset management. Developed in strict compliance with DIR (Doing It Right) guidelines, this kit not only provides primary and backup breathing apparatus but also integrates a submersible pressure gauge (SPG) system with a metal pressure gauge. Based on the proven R2 balanced diaphragm first stages with a 360° swiveling turret and a 5th axial LP port, it ensures perfectly parallel and tension-free hose routing. Certified to EN250A, it is the ideal choice for deep technical, cave, and ice diving.

Technical Features:

• Dual R2 TEC First Stages (Maximum Geometric Cleanliness): Made from solid chrome-plated marine bronze, the two first stages utilize a balanced diaphragm mechanism with a sealed dry chamber for anti-freeze protection. The rotating turret combined with the axial fifth low-pressure port (on the head of the first stage) allows for clean and linear hose routing along the cylinder profile, eliminating forced bends in the hoses behind the neck. Each first stage offers 5 LP and 2 HP ports.
• Dual TEC1 Second Stages (Precise and Stable Delivery): The pneumatically balanced second stages drastically reduce inspiratory effort at any depth. They are protected by an anti-impact aluminum peripheral ring and feature a classic, extremely reliable dome design.
• 52mm Metal SPG Technical Pressure Gauge: The set includes a professional submersible pressure gauge with a chrome-plated brass casing and a 52mm tempered glass. Featuring a highly readable luminescent face, it is coupled with a black high-pressure (HP) hose with customizable length (0.57 m, 0.60 m, or 0.65 m).
• Flow Control and Safety: Both second stages integrate a lever for managing the Venturi effect (essential to prevent free-flows on the neck-mounted second stage) and a micrometric knob for adjusting breathing resistance, supported by a dedicated anti-freeze heat exchanger.
• Customized DIR Style Hose Geometry: The included low-pressure hoses are precisely sized for their technical roles: a long hose of 1.93 m, 2.00 m, or 2.10 m for the primary donor and a short hose of 0.61 m for the neck-mounted backup.
