DUTY-GRADE BUILD.
SECOND-GEN PISTON. EDGE LOCK RETENTION. METERED CONTROL.
J01 series is built on a Second-Generation Piston Architecture for metered, gradual control through the usable stroke, with improved response even as deposits build. Edge Lock System uses lateral retention to keep the inflation assembly compact, create room for larger buttons, and simplify maintenance.
Driven Seal Exhaust brings a smoother, more progressive release response to the system.
A smoother control progression, more readable input, and a cleaner, more defined control feel.

AVAILABLE SYSTEM CONFIGURATONS
Specify your setup. Each HYDPRO Tek Range series is offered in three Actuation Core configurations: Metal, Technopolymer, and Non-Magnetic. Non-Magnetic also available to Military & Defence specification on a program basis.
Metal Actuation Core
Built around precision machined metal alloy buttons and internal components, this configuration is engineered for high structural strength and impact resistance. Designed for heavy duty use, it delivers mechanical reliability and long term durability in demanding operational conditions.
Extended Mount Compatibility
Engineered for cross-platform integration, HYDPRO Power Units are available in T23 and T25 Mount Standards, specifically configured for 23.6 mm (0.93 in) and 25.4 mm (1.00 in) corrugated hoses.
ENGINEERED FOR BALANCE. FORGED FOR CONTROL.
ITALIAN ENGINEERING.
PREDICTABLE CONTROL.
Each HYDPRO device is engineered and manufactured in Italy: one chain from raw material to release. Polymer families are selected for constant immersion, precision-drawn brass runs on in-house CNC lines, and every device leaves built, tested, and signed off under one roof.
Built to integrate. True to your setup.
Whatever the field runs, HYDPRO builds to it natively: every established mount standard, thread, and host geometry, covered from the factory. Your setup stays as it is, integration stays clean, and the response repeats: the same command, the same result, on every dive.
Proven by divers. Refined by decades.
Four decades in the water stand behind the current generation. What wears, what binds, what drifts out of tune comes back from real dives to the bench, and the next revision answers it. Control you can feel, refined one generation at a time.
