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.
