Celebrated across the scuba industry for its bulletproof durability, uncomplicated design, and low maintenance demands, the Scubapro MK2 EVO First Stage Regulator - DIN (1st Stage Only) is the ultimate workhorse first stage. Equipped with a dedicated 300-bar DIN handwheel and Scubapro’s patented Extended Thermal Insulating System (XTIS), this classic downstream piston first stage provides reliable air delivery for dive training, rental fleets, decompression stage bottles, and travel setups.
Secure 300-Bar DIN Fitting & Patented XTIS Thermal Protection
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. Integrated with Scubapro's patented XTIS (Extended Thermal Insulating System), the internal mechanical components are fully insulated from the cold-water environment, increasing freezing resistance by up to 50% compared to standard downstream piston designs without adding complexity or weight.
Features and Benefits
- Dedicated 300-Bar DIN Connection: Direct-threaded DIN handwheel provides a lighter, more secure, and higher-pressure cylinder interface preferred for modern steel cylinders and stage bottles.
- Classic Downstream Piston Design: Time-tested, reliable mechanism built with fewer moving parts for simplified servicing and legendary longevity.
- Patented XTIS Thermal Insulation: Fully insulates internal moving parts from the environment, radically delaying ice formation in cold waters and fully meeting EN250A cold-water standards.
- Rugged Chrome-Plated Brass Body: Heavy-duty marine brass casing resists scratches, impact damage, and harsh saltwater corrosion.
- Optimized Hose Port Layout: Features 4 low-pressure (LP) ports and 1 high-pressure (HP) port positioned cleanly around the body for streamlined hose routing.
- Removable Stainless Steel Valve Seat: Extends service life by allowing easy seat replacement during routine overhauls.
