Your powerful, effective choice for increasing penis size and erection strength.

Bathmate's original pump and perpetual best-seller, the Hydro7 (Hercules) uses water to create a vacuum for maximum gains in length and girth.

It's ideal for beginners with a current erection length between five and seven inches.

Just fill the hydropump with warm water, seal it against your body for three five-minute sessions to start your penis expansion routine.

The patented hydraulic bellows release the pressure slowly over time, making it safe to use. Made from high-quality materials including a toughened polycarbonate tube with a quick-release valve for ease of use.
