The Scubapro MK19 EVO Yoke is a high-performance balanced diaphragm first stage regulator, purpose-built for the demands of cold-water, deep, and contaminated diving environments. Designed by Scubapro’s R&D team in Italy, this regulator reflects the growing needs of the technical diving community—delivering uncompromising reliability, enhanced airflow, and superior hose routing flexibility.

Unlike piston designs, balanced diaphragm regulators are environmentally sealed, preventing water, salt, silt, and other contaminants from entering the internal mechanism. This makes the MK19 EVO ideal for cold water and polluted conditions, while still delivering smooth, high-volume airflow at any tank pressure or depth.

Key Features

Balanced Diaphragm Design
Maintains consistent performance and airflow, unaffected by tank pressure or depth.

Environmentally Sealed Dry Chamber
Protects internal components from freezing and contamination, extending service life and improving reliability.

Compact and Lightweight
Smaller and lighter than the original MK19 and competing models, ideal for travel and technical setups.

Rotating Swivel Turret
Features 4 high-flow LP ports for streamlined hose routing, plus 1 axial super high-flow LP port for demanding air delivery needs.

Two 7/16" Threaded HP Ports
Allow for redundant pressure monitoring or transmitter setups.

Thermal Insulating System (TIS)
Reduces the risk of freezing during low-temperature dives.

Premium Construction
Machined from marine-grade chrome-plated brass for long-term durability in harsh environments.
