Complete Sidemount Configuration. Built for Total Control.

The Tecline R2 TEC2 Sidemount Set is a purpose-built regulator system designed specifically for sidemount diving, combining two R2 balanced diaphragm first stages with two TEC2 second stages and the hoses, gauges and accessories needed for a clean, functional sidemount configuration.

Rather than adapting a conventional regulator setup to sidemount, this configuration is designed around the requirements of side-mounted cylinders, with the R2’s rotating turret and fifth low-pressure port helping create clean and practical hose routing.

Designed Specifically for Sidemount

At the heart of the system are two R2 TEC first stages, each featuring a balanced diaphragm design, rotating turret and fifth low-pressure port. The additional port is particularly useful for sidemount configurations, allowing the regulator hoses to be routed neatly around the diver and cylinders.

Each first stage provides two HP and four LP connections, with the fifth LP connection available through the rotating assembly. The R2 is rated for working pressures up to 300 bar, giving it the flexibility required for a variety of cylinder configurations.

Two Independent Breathing Systems

The set includes two balanced TEC2 second stages, providing a separate breathing system for each sidemount cylinder.

The TEC2 features:

• Pneumatically balanced design
• Venturi adjustment
• Adjustable breathing resistance
• Direct Flow System
• Ergonomic mouthpiece
• Stainless-steel protective ring
• Compact, lightweight design

The second stages are designed to provide smooth, controlled breathing while remaining practical for demanding diving environments.

A Complete Sidemount Setup

The R2 TEC2 Sidemount Set includes the components needed to create a purpose-built regulator configuration rather than requiring the diver to assemble the system piece by piece.

Included in the Set

• 2 × R2 TEC first stages with fifth LP port
• 2 × TEC2 second stages
• 2 × 90° swivels
• 2 × 65–70 cm LP hoses
• 2 × 20 cm LP inflator hoses
• 2 × 20 cm HP hoses
• 2 × 52 mm SPGs, 300 bar
• 1 × 88 mm stainless-steel bolt snap
• 1 m of 4 mm bungee
• Tecline regulator bag

Exact hose lengths and bag configuration may vary between supplied versions, so confirm the configuration when ordering.

Built for Clean Hose Routing

Sidemount is all about configuration.

With cylinders positioned alongside the body, poorly routed hoses can create unnecessary bulk, snag points and access problems. The R2’s rotating first-stage design and additional fifth LP port give divers greater freedom to route hoses cleanly around their cylinders and body.

The included 90° swivels further help position the second stages naturally, keeping the regulator system streamlined and accessible.

Built Around the Way You Dive

Sidemount isn’t simply about moving your cylinders to your sides. The entire equipment configuration needs to work together.

The Tecline R2 TEC2 Sidemount Set brings the regulators, hose routing, gauges and essential accessories together into one purpose-built system, giving you a clean and adaptable foundation for sidemount diving.

From recreational exploration to demanding caves and wrecks, it’s a regulator configuration designed to stay organised, accessible and ready for the dive.

Two cylinders. Two breathing systems. One streamlined configuration.
