REV P04 Keen

P04 Series Core, low-profile clearance with pull-actuated exhaust.

REV P04 Keen REV P04 Keen REV P04 Keen REV P04 Keen

Pull-actuated exhaust is integrated into a low-profile body with an elliptical hose interface, reducing bulk and snag exposure. Built to the P04 flange interface, it fits natively across P04 Series flanges.

REV P04 Keen — 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.

INFLATOR SYSTEM · CONNECTOR UNITS

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.

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.
