Sidemount Regulator Set R2 TEC1

The complete and proven Sidemount system based on a pair of R2 TEC first stages with a balanced diaphragm, a 360° swiveling turret, and a 5th axial port. Paired with pneumatically balanced TEC1 second stages, it ensures ultra-clean hose routing, Dry Chamber protection for cold water, and consistent breathing comfort. Customize hose configuration from the dropdown menu.

The Tecline R2 TEC1 Sidemount Set, available on DIR-STORE, is one of the most popular solutions for technical and recreational divers for setting up side-mounted cylinders.

The architecture of the R2 TEC first stages combines the dry chamber (Dry Chamber) — ideal against freezing and suspended particles — with the versatility of a 360° swiveling turret equipped with a 5th axial LP port. This layout allows for parallel hose routing along the cylinders, eliminating forced bends. The pneumatically balanced TEC1 second stages ensure smooth, controllable, and effortless delivery even at great depths.

Key Features for Sidemount:

2x R2 TEC Dry Chamber First Stages (Balanced Diaphragm / DIN 300 bar):

• Antifreeze & Dry Chamber Protection: Isolates internal mechanisms from water and sediment, perfect for demanding dives and cold water.
• Optimized Sidemount Layout: 360° swiveling turret with 5 LP ports (including the 5th axial on the head) and 2 symmetrical HP ports for hydrodynamic and parallel hose routing.
  

2x TEC1 Black Second Stages (Balanced):

• Pneumatic Balance: Ensures constant airflow and minimizes breathing effort.
• Dual Control: Equipped with micrometric adjustment of initial inhalation effort and a Venturi lever to zero out accidental free-flow when the cylinder is not in use.

Hose Geometry and Included Sidemount Accessories:

• Regulator Hose Configuration: 1.93 m long hose for the primary and 0.65 m short hose for the backup second stage under the chin.
• 90° LP Swivel: Mounted on the secondary second stage for ergonomic and tension-free positioning at the mouth.
