OVERVIEW
MK21 DIN Regulator First Stage Only
FEATURES
- Air-balanced flow-through piston provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate
- Polished chrome-plated marine grade brass body is close to 20% smaller than the MK25, making it an easy travel companion
- Unique thermal exchange design with external fins optimizes freezing resistance
- Two high pressure ports, one on each side of the body, allow the first stage to be positioned either up or down
- Standard "smart" hose routing cap offers four low pressure ports angled for more convenient hose routing (+/- 20°)
- Optional hose routing cap increases routing configurations with four angled low pressure ports (0°/30°) plus a fifth centralized high-flow low pressure port, ideal for technical diving
- Redesigned yoke allows for easier mounting on a cylinder, and a redesigned cap protects internal components from water intrusion after the dive
