Premium Hydraulic Penis Pump — Bathmate HydroXtreme 9 X40

The Bathmate HydroXtreme 9 is the most powerful version in the range—the X40 indicates an internal diameter of 40 mm, designed for experienced users. The transparent hydraulic pump with a red hose and gray pressure valve is the most efficient system on the market for water-assisted erections.

Hydraulic, not pneumatic—that changes everything

The pressure created by water is more uniform and gentler than air. You use the pump in the shower or bath: fill the cylinder with water, pump to create suction, and leave it on for up to 15 minutes max per session. The difference in volume after a session is immediately visible. With regular use, results accumulate.

The safety valve that makes all the difference

The gray tip at the bottom includes a safety valve that releases pressure in case of over-pumping—a detail that low-end pumps don't have. The red hose connects to empty the cylinder without you having to get up. Bathmate delivers the pump with its storage pouch and user guide.
