DIR Regulator Set – 1st Stage R4WW + 2nd Stage TEC2 + Pressure Gauge

Complete twinset configuration compliant with DIR standards, equipped with two R4WW monolithic diaphragm first stages for temperate waters, top-of-the-range ultra-compact second stages, a metal pressure gauge, and an accessories kit.

The Tecline R4WW TEC2 + SPG DIR Set Regulator, available on DIR-STORE, is the premium, ready-to-use technical package developed for divers who demand a precise and clean twinset layout in temperate or warm waters. This system combines the structural solidity of the monolithic R4WW first stages (without moving rotating turrets) with the advanced fluid dynamics of the TEC2 second stages, also including the pressure control system (SPG) with a metal submersible pressure gauge. In full compliance with the DIR (Doing It Right) philosophy, the pre-inclined routing ensures all hoses run linearly and parallel along the cylinders, minimizing friction and freeing the neck from obstructions.

Technical Features:

• Dual R4WW First Stage (Fixed Warm Water Design): Constructed from robust chrome-plated marine bronze, the R4WW first stages utilize a balanced diaphragm mechanism specifically optimized to maximize gas flow in non-arctic contexts, excluding the sealed dry chamber. The fixed arrangement of the inclined radial outlets allows for perfect DIR routing, allowing the hoses to run straight down the profile of the buoyancy compensator's bladder without generating structural tension. Each first stage offers 4 LP and 2 HP ports.
• Dual TEC2 Second Stage (DFS Technology and Ultra-Comfort): The pneumatically balanced second stages implement the innovative DFS (Direct Flow System) direct flow system. This architecture optimizes the internal fluid dynamics of the gas, minimizing overall inspiratory effort at any depth, regardless of the residual pressure in the cylinders.
• Second Stage Structure and Protection: The structural polymer casing is shielded at the front by a solid stainless steel ring to resist strong mechanical stress or impacts in caves. The internal metal parts benefit from a non-stick Teflon protective coating.
• Technical SPG 52mm Metal Pressure Gauge: The set includes a professional submersible pressure gauge with a chrome-plated brass case and 52mm tempered glass. Equipped with a luminous, high-readability dial, it is paired with a black high-pressure (HP) hose of customizable length (0.57 m, 0.60 m, or 0.65 m).
• Dual Adjustment and Safety: Both second stages integrate a Venturi control lever (essential for inhibiting accidental free flows on the backup second stage around the neck) and a micrometric knob for manually calibrating the inspiratory effort.
• Custom DIR Style Hose Geometry: The included LP hoses faithfully follow the technical standard: a long hose (1.93 m, 2.00 m, or 2.10 m) for the primary second stage (the donor) and a short hose (0.61 m) for the neck backup.
