The Tecline TEC2 O₂ Green is a high-visibility, high‑performance second stage designed specifically for decompression gases and high‑percentage O₂ mixtures. Featuring a high‑flow balanced downstream valve, Venturi control, breathing resistance adjustment, an ergonomic mouthpiece, and a reinforced aluminium outer ring, it delivers exceptional breathing comfort and EN250A‑certified reliability. Its distinctive green body ensures clear identification as an oxygen‑dedicated regulator for safe technical decompression procedures.

High‑flow balanced downstream valve

The TEC2 is built around a high‑flow balanced downstream valve, offering increased gas delivery compared to the TEC1 series.

• Effortless breathing at all depths
• High‑flow performance for demanding technical dives
• Stable airflow under heavy workload
• Optimised for cold‑water and deep environments

High‑visibility green design

The bright green body ensures instant recognition as an oxygen regulator.

Prepared specifically for oxygen service, the TEC2 O₂ Green is suitable for high‑percentage oxygen mixtures used during decompression.

• Distinct green colour coding for safe identification
• Ideal for technical decompression protocols
• Designed for dedicated O₂ stage cylinders

Breathing resistance adjustment

The TEC2 includes a user‑adjustable breathing resistance knob, giving divers precise control over inhalation effort.

• Fine‑tune breathing comfort
• Increase resistance for surface conditions
• Reduce resistance for deep or extended decompression stops
• Supports personalised breathing comfort
