Stage Regulator Set – 1st Stage R4 + 2nd Stage TEC1 + Pressure Gauge

The universal dry chamber (antifreeze) regulator kit designed for equipping stage/deco cylinders in any condition, including cold water dives. It combines the thermal insulation of the R4 TEC first stage with the fluidity of the pneumatically balanced TEC1 second stage. Customize the type of LP hose and select the size and material of the HP hose from the dropdown menu.

The Tecline R4 TEC + TEC1 + SPG Stage Regulator Set, available on DIR-STORE, is designed for those seeking an extremely reliable and freeze-protected (free-flow) system for their bailout or decompression cylinders.

Unlike wet chamber models, this set uses the balanced diaphragm R4 TEC first stage with a dry chamber, which isolates the internal mechanisms from icy water and suspended particles. It is paired with the Black TEC1 second stage, a pneumatically balanced regulator that offers exceptionally smooth and modulable breathing at any depth.

Key Features of the Set:

R4 TEC Dry Chamber First Stage (Antifreeze Protection):

• Balanced Diaphragm with Dry Chamber: Isolates the spring and piston from direct contact with water. Ideal for winter diving, cold water, or in the presence of sediment.
• Constant Pressure: Ensures a balanced and high-performing airflow at any depth and with any residual cylinder pressure (DIN 300 bar connection, 4 LP ports / 2 HP ports).
• Chrome Plated Marine Bronze Body: Robust, hydrodynamic, and ultra-resistant to corrosion.

Black TEC1 Second Stage (Smooth and Balanced Delivery):

• Pneumatic Balance: Reduces initial breathing effort while maintaining a consistently smooth and constant airflow.
• Dual Adjustment: Equipped with a micrometric knob for initial inspiratory effort and a lever for managing the Venturi effect (essential for preventing free-flow when the stage is attached to the rig and not in use).
• Ergonomic Design: Impact-resistant technopolymer casing with a wide exhaust tee that diverts bubbles away from the field of vision.

Technical SPG 52 mm Pressure Gauge: Compact analog instrument with a 52 mm metal casing for clear and immediate reading of stage gas pressure.

🛒 Customization: Configure the perfect routing for your stage from the dropdown menu:

• Regulator LP Hose: Fixed length of 100 cm. You can choose between the classic Thermorubber or the Proflex flexible hose (supplied as standard in black Proflex).
• Pressure Gauge HP Hose: Choose the short stage size (15 cm or 20 cm) and the material type between Thermorubber or Miflex.
