Scubapro MK25 EVO Regulator- 1st Stage Only

The Scubapro MK25 EVO first stage is a regulator component for scuba diving gear, delivering a fast breathing response and reliable air on demand for underwater diving performance in challenging conditions.

Its patented XTIS Extended Thermal Insulating System isolates the mechanical elements from the cold, increasing freezing resistance by 30 percent without compromising breathing performance. Key insulation system components are visible in blue to indicate the enhanced cold-water protection.

Designed for dependable underwater use, the MK25 EVO features an air balanced flow-through piston in a chrome-plated brass body, anti-freeze protection, and a suite of insulation enhancements that work together to improve cold-water performance and breathing reliability in extreme temperatures.

Port configuration supports versatile setup: two opposing high-pressure ports allow orientation up or down, and five high-flow low-pressure ports on a swivel turret maximize hose routing options. External intermediate pressure adjustment enables quick, precise tuning for a range of diving scenarios. Available in either 3364psi/232bar INT or 4350psi/300bar DIN configurations.

For scuba enthusiasts and underwater gear configurations, the MK25 EVO offers robust airflow and precise performance: airflow at 2900psi/200bar > 8500 l/min / 301 SCFM; intermediate pressure 133-142 psi / 9.2-9.8 bar. Weight is INT 27.9 oz / 790 g and DIN 20.1 oz / 570 g.

• Air balanced flow-through piston in a chrome-plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• Patented XTIS (Extended Thermal Insulating System) fully isolates the mechanical elements from the cold, increasing freezing resistance 30 percent over the previous MK25 without compromising breathing performance. Key insulation system components are visible in blue.
• New spring insulating coating, body insulating bushing, anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water performance.
• Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.
• Two opposing high-pressure ports allow the first stage to be positioned either up or down.
• Five high-flow low-pressure ports on a swivel turret maximize hose routing options.
• External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
• Available in either 3364psi/232bar INT or 4350psi/300bar DIN configurations.
• Weight: INT 27.9 oz / 790 g; DIN 20.1 oz / 570 g.
• Airflow at 2900psi/200bar: >8500 l/min / 301 SCFM.
• Intermediate pressure (psi/bar): 133-142 / 9.2-9.8.
