Hydromax 5

An 8-Inch Cylinder Sized for Lengths of 3 to 5 Inches

An 8-inch internal length and a rigid ABS plastic body define this hydro pump. The cylinder is intended for men with a penis length between 3 and 5 inches, so the fit is built around that range rather than a single size.

ABS is a firm, impact-resistant plastic. The shell stays stiff while the bellows does the flexing, and that split between a solid outer body and a flexible inner section shapes how the pump handles during use.

Bellows and Soft Pads That Hold a Seal With Less Pumping

The bellows is larger than in earlier designs, and it has fewer convolutions. That combination makes it more flexible while keeping it strong. The result is greater suction for less effort, rated at 35% more suction power than the earlier Hydro7.

At the opening, soft comfort pads form the seal. The outer edge is soft-touch, while the inner tube stays rigid to shield the penis. A tighter seal means less pumping is needed and less suction is lost. Every pad is removable, so each piece can be taken apart for cleaning.

A Locking Valve for Filling With One Hand

The water valve has a latch or switch that closes it, stopping water from escaping while you fill the cylinder. You can fill the device using only one hand, leaving the other free for adjustments or for reaching accessories.

The clear option is see-through, which lets you monitor the cylinder while you pump. Keep the rigid ABS body away from sharp edges and rough surfaces so the shell stays intact.
