Extended Mount Compatibility

Engineered for cross-platform integration, HYDPRO Connector 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.

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.

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.
HYDPRO power unit manufacturing: CNC machining, hand assembly, and the finished valve underwater

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.
