These Pump Cylinders are comfortable devices for the increase of your penis size. You don't need to use any gaskets, plus each cylinder has a state-of-the-art air valve which means you can disconnect the cylinder from the pump without sacrificing you new increased size.

Most men will require the 2 inch diameter cylinder. If your equipment is leaning towards small we recommend the 1.75 diameter cylinder. Likewise, if you're above average the 2.25 cylinder would be your choice.

Note: Pump and tube are not included. See our Premium Penis Pump Kit below for a complete package.
