The MK11/S270 INT regulator system delivers reliable, compact air delivery for scuba and underwater diving scenarios. The 1st stage uses a diaphragm-balanced design to maintain steady performance regardless of depth or tank pressure, while the 2nd stage S270 provides smooth breathing with an air-balanced valve. This pairing supports consistent airflow across varied conditions and gear configurations.

Built for rugged use in wet environments, the 1st stage is chrome-plated brass. The 2nd stage housing uses a fiberglass-reinforced nylon core with a PU outer layer for durability. The INT connector enables standard hose compatibility, and the system supports Nitrox up to 40%. With 2 HP ports and 4 LP ports, it accommodates common scuba gear configurations, while a lightweight design and a compact exhaust tee minimize exhalation effort. It is suitable for cold and temperate water use, and the setup weighs about 3.1 lb.
