Designed specifically for extreme cold-water performance, ice diving, and silty or contaminated environments, the Scubapro MK17 EVO First Stage Regulator - DIN (1st Stage Only) pairs proven environmentally sealed freeze protection with a dedicated 300-bar DIN connection. As an air-balanced diaphragm first stage, the MK17 EVO delivers instant, effortless airflow regardless of depth, breathing rate, or tank pressure while isolating internal mechanical parts completely from the elements.
Secure 300-Bar DIN Connection & Environmentally Sealed Dry Chamber
The factory 300-bar DIN handwheel threads directly into high-pressure cylinder valves for an ultra-secure, captive O-ring seal rated up to 4350 psi. Paired with a completely dry ambient chamber that isolates the mainspring and mechanical parts from freezing water, salt crystals, and suspended silt, the MK17 EVO delivers flawless, freeze-resistant reliability on every dive.
Features and Benefits
- Dedicated 300-Bar DIN Connection: Direct-threaded DIN handwheel provides a lighter, more secure, and higher-pressure cylinder connection preferred for cold-water and technical diving.
- Environmentally Sealed Dry Chamber: Isolates internal mechanical parts from the surrounding water to prevent freeze-ups and block sand, silt, and chlorine contamination.
- Air-Balanced Diaphragm Mechanism: Delivers ultra-smooth, constant airflow completely unaffected by tank pressure or recreational depth.
- High-Flow Low-Pressure (HFP) Ports: Four LP ports configured to deliver maximum gas volume to primary and octopus second stages.
- Dual High-Pressure (HP) Ports: Angled opposing HP ports accommodate a wireless tank transmitter and an analog pressure gauge on either side.
- Optimized Hose Routing: Fixed-port body geometry angles all LP and HP hoses cleanly around the tank valve to minimize drag and prevent snagging.
- Durable Chrome-Plated Brass Body: Built from heavy-duty marine-grade brass for exceptional corrosion resistance and longevity.
