Tecline R5 TEC1 Regulator Set I with Octopus and SPG – EN250A
The R5 TEC1 regulator set is a complete, technical-oriented solution designed for cold water, recreational, and technical diving. The configuration follows a clean and proven TEC philosophy, focusing on reliability, simplicity, and long-term performance in demanding environments.
The set is EN250A certified, making it suitable for cold water diving and for supplying air to two divers from a single first stage.
First Stage – R5
The R5 is a balanced diaphragm first stage that provides consistent intermediate pressure across the full cylinder pressure range. The diaphragm design isolates internal components from water and contaminants, making it ideal for technical, cave, and wreck environments.
Key features:
- balanced diaphragm design
- environmentally sealed (dry sealed) construction
- reduced risk of freezing
- reliable performance in cold and contaminated water
Port configuration:
- 4 low-pressure (LP) ports
- 2 high-pressure (HP) ports
The port layout supports long hose and technical configurations.
Second Stage – TEC1
The TEC1 second stage features a pneumatically balanced design, delivering smooth and effortless breathing even under heavy demand. Its robust construction and simple internal layout make it a popular choice among technical divers.
Features:
- stable breathing performance at all depths
- durable housing for long service life
- large purge button, easy to operate with gloves
- fixed Venturi design to reduce unwanted freeflows
Octopus – TEC1
The set includes a TEC1 octopus, built on the same reliable platform as the primary second stage. Its high-visibility color and simple operation provide a dependable air source in emergency situations.
SPG – 52 mm Pressure Gauge
An analog 52 mm submersible pressure gauge is included, offering accurate and easy-to-read cylinder pressure monitoring. It serves as an ideal redundant pressure indication for both recreational and technical divers.
Hoses
The regulator set is supplied with factory hoses:
- LP 0.70 m Proflex hose, black
- LP 0.90 m Proflex hose, yellow (octopus)
- HP 0.80 m rubber hose, black
Proflex hoses are flexible, lightweight, and well suited for technical setups.
