Description
The R2 TEC2 21% O2 G5/8 regulator with pressure gauge is intended for stage tanks. The R2 TEC first stage is a balanced diaphragm design with a dry chamber that seals the working diaphragm and prevents freezing in cold water; this protection is also an advantage in heavily silted water. It is made of marine brass with a high-quality frosted chrome finish. The rotating turret allows flexible hose routing, and on a stage tank the hoses can be stowed neatly along the tank and deployed to their full length when needed.
