Set Stage Oxygen 100% S40 MES

The light and compact decompression kit, ready for use and ideal for use with oxygen or hyper-oxygenated mixtures. Includes a 5.7 liter MES S40 aluminum cylinder, a Scubatec valve of your choice (M25x2 or M26x2), a complete stage harness, a 52 mm O2 pressure gauge with Viton swivel, and a green regulator bag. Configure your set by choosing your preferred first stage from Scubatec's F22, F30, F32 or Tecline's R2 (all equipped with a swivel turret and pre-arranged for a 5th port) and pair it with a REC1, TEC1, TEC2 or FX3 second stage.

The S40 MES Aluminum Cylinder with O2 Regulator, available on DIR-STORE, is the ideal choice for technical divers looking for an extremely compact and lightweight accent or travel decompression cylinder. With its 5.7 liter volume, the S40 offers a perfect balance between decompression gas supply and hydrodynamics. This kit makes customization its strong point: it allows you to choose the heart of the delivery system by selecting from four of the best balanced diaphragm first stages on the market, all characterized by the presence of a 360° swivel turret with an option for a fifth port (axial LP outlet on the head). Every component is fully compatible with high-concentration oxygen, including the Viton swivel of the pressure gauge.

Key Features:

• MES S40 Aluminum Cylinder (5.7 LT) and Valve of Choice: Produced by the prestigious MES brand, this aluminum cylinder is renowned for its lightness out of the water and its neutral/positive buoyancy during diving. It is equipped with a high-quality Scubatec valve, selectable with a standard M25x2 thread or an oxygen-specific M26x2 (compliant with European regulations).

Four First Stage Options (Swivel Turret & 5th Port): Configure your hose routing without compromise. You can choose the ideal first stage for your layout from:

• Scubatec F22: The great classic, solid and super tested.
• Scubatec F30: High-performing, with a compact body designed for optimal airflow.
• Scubatec F32: Top-of-the-range model with elite finishes and excellent thermal dissipation.
• Tecline R2: Absolute versatility with a sealed dry chamber kit (Dry Chamber) and advanced antifreeze.

All selectable first stages are balanced diaphragm, feature a 360° swivel turret, and support the installation of an axial 5th LP port for linear routing.

• Second Stage Choice (REC1, TEC1, TEC2 or FX3): Customize delivery based on your preferences. Choose the reliable balanced TEC1 second stage, or the advanced TEC2 with DFS direct flow technology for maximum breathing comfort, or the lightweight REC1 or the functional FX3 Scubatec.
• Complete Stage Harness (Rigging Kit): The kit includes a professional pre-assembled stage harness consisting of elastic hose retainers, high-strength line, marine-grade stainless steel single-loop snap hooks, and a protective cylinder cover.
• 52 mm O2 Pressure Gauge with Viton Swivel: Precision analog instrument with a 52 mm metal case and high-visibility dial, cleaned for O2 use. The internal swivel is equipped with Viton O-rings, a material specifically designed to resist the oxidizing action of pure oxygen.
• Green Tecline Regulator Bag: Elegant and robust padded case coordinated in green, ideal for immediately identifying your oxygen-dedicated regulator and protecting it during storage and transport.

Customization: On DIR-STORE you can configure your light decompression kit down to the smallest detail. Select the first stage model (F22, F30, F32 or R2), the Scubatec valve thread (M25x2 or M26x2), the second stage model (REC1, TEC1, TEC2 or FX3), the type/color of the 100 cm LP hose, and the length of the HP pressure gauge hose (15 cm or 20 cm in rubber or Miflex) directly from the dropdown menu before adding the product to your cart!
