Octopus Set – 1st Stage F50 + 2nd Stage FX3 + Pressure Gauge

Advanced recreational balanced diaphragm configuration with lamellar radiator head, ideal for cold waters, thermoclines, and high-efficiency octopus setups. Includes F50 fixed-body first stage with ABS bezel, FX3 primary and octopus second stages, compact 52mm pressure gauge, and customizable hoses.

The Scubatec F50 FX3 + SPG Regulator Set, available at DIR-STORE, is a high-quality respiratory system entirely Made in Italy, designed to ensure maximum safety, flow stability, and reliability even at great depths. The heart of this kit is the F50 first stage, a solid balanced diaphragm fixed-body reducer that stands out for integrating a lamellar radiator on the head. This engineering solution increases the metallic contact surface with the external environment, optimizing heat exchange and counteracting temperature drops due to gas expansion. It is the perfect choice for advanced recreational diving in lakes, springs, or cold seas. Paired with the adjustable FX3 second stages, it ensures abundant, smooth, and effortless delivery at any stage of the dive.

Technical Features:

• F50 First Stage (Balanced Diaphragm and Lamellar Radiator): Constructed from solid chrome-plated marine brass with a robust ABS bezel (DIN 300 bar connection), the F50 first stage ensures a perfectly constant intermediate pressure calibrated at approximately 10 bar, regardless of depth or gas reserve. The native thermal protection of the radiator head effectively prevents freezing (free-flow) phenomena. For extreme winter or under-ice conditions, it is still pre-arranged for the optional installation of the dedicated sealed Anti-Freeze Kit.
• Rational and Symmetrical Outlet Layout (4 LP / 2 HP): The first stage features a fixed body with 4 symmetrically arranged LP (3/8" UNF) outlets calibrated to cleanly and ergonomically supply the primary second stage, octopus, BCD, and dry suit, ensuring excellent stability in emergency flows. The body is completed by 2 HP (7/16" UNF) outlets for simultaneous connection of analog pressure gauges and computer transmitters.
• Customization Options (Gas and Connection): In full compliance with European standard EN 250:2014, the set supports maximum customization during ordering. The first stage can be configured with standard NBR compound O-rings or in the elite version with Viton O-rings and oxygen-compatible grease for safe use with Nitrox mixtures.
• Dual FX3 Second Stage (Micrometric Regulation and Robustness): The FX3 second stages offer maximum reliability and durability. They integrate a side knob for manual adjustment of initial breathing effort and a lever for Venturi flow control, allowing the diver to calibrate the regulator's sensitivity to the millimeter based on depth and preventing accidental continuous flows when the octopus is not in use.
• Octopus and Visual Layout: To ensure maximum team safety and immediate identification, the primary second stage comes in the classic black color, while the backup second stage (Yellow FX3) features a high-visibility yellow front cover.
• SPG 52 mm Technical Pressure Gauge: The kit includes a professional and compact analog pressure gauge, featuring a 52 mm diameter metal case and a high-readability dial for quick reserve monitoring. It comes with a heavy black rubber high-pressure (HP) hose of 0.80 m.
• Hose Flexibility: The set is configured as standard with a 0.70 m LP hose for the primary second stage (black color) and a 0.90 m LP hose for the octopus (black color).

Note for purchase: At DIR-STORE, you can customize your configuration by choosing the length and type of hoses (e.g., rubber or Miflex) best suited to your diving style before completing your order!
