Penis Pump Cylinders

Our original Flared Expansion Cylinders have a small restriction at the opening, just inside the curved lip. This restriction produces an effect similar to a cock ring – allowing an immediate expansion in thickness right at the beginning of your vacuum session. Our ThickWall cylinders go in deeper to the pubic bone, helping with length. Our newest Oval shaped Elliptical Cylinders are more anatomically correct. This wonderful match between your shape and the matching shape of the cylinder produces amazing results. We have many sizes and types from small to gigantic. Be sure to consult our How to Measure chart for your cylinder type to select your perfect cylinder size.
