Stage Regulator Set – 1st Stage R4 + 2nd Stage REC1 + Pressure Gauge

The ideal dry chamber (antifreeze) universal regulator kit for setting up stage/deco cylinders in any environmental condition, including the coldest waters. It combines the thermal insulation of the R4 TEC first stage with the ease of use of the REC1 second stage. Customize the type of LP hose and select the size and material of the HP hose from the drop-down menu.

The Tecline R4 TEC + REC1 + SPG Stage Regulator Set, available on DIR-STORE, is designed to ensure maximum reliability and complete protection from the risk of freezing (free-flow) during decompression phases or when using pony bottles.

Unlike the WW version, this set uses the R4 TEC balanced diaphragm first stage equipped with a dry chamber, which completely isolates the internal mechanisms from freezing water and sediments. It is paired with the black REC1 second stage (only 195 grams), an essential, robust regulator factory-preset to offer consistent and safe delivery without distractions or adjustable knobs.

Key Features of the Set:

R4 TEC Dry Chamber First Stage (Antifreeze Protection):

• Balanced Diaphragm with Dry Chamber: Completely isolates the spring and piston from water. Ideal for cold water diving and environments with suspension or sediment.
• Constant Pressure: Ensures a constant and high-performance airflow at any depth and with any residual cylinder pressure (DIN 300 bar connection, 4 LP ports / 2 HP ports).
• Chromed Marine Bronze Body: Robust, hydrodynamic, and resistant to the corrosive action of salt.

REC1 Black Second Stage (Simplicity and Lightness):

• Pre-Set Delivery: Essential design with no external adjustments for maximum operational simplicity and immediate reliability.
• Venturi Lever (On/Off): Allows for zeroing accidental free-flow when the stage cylinder is attached to the diver's sides and not in use.
• Polyamide Casing (195 g): Drastically reduces the overall weight of the configuration and jaw fatigue.

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

🛒 Custom Personalization: Configure the perfect routing for your stage from the drop-down menu:

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