Description
The R4 TEC2 oxygen regulator, for use with up to 100% oxygen. The R4 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 design is popular on stage tanks for technical diving, as the hoses can be stowed neatly along the tank and deployed to their full length when needed.

- R4 TEC 100% O2 M26x2 first stage
