Penis Pump Cylinder Size Chart

The best way to determine which cylinder size of our penis pumps is right for you, is to measure the circumference of your erect penis. The circumference is the circular distance around your penis.

If you do not have a measuring tape to do this, you can also use a string, shoelace or dental floss and wrap it loosely around the thickest part of your penis while in an erect state. Mark the string where it makes a complete circle, and place the string out flat next to a ruler. Measure the distance between the markings, this length is your penis circumference.

Once you know your circumference, simply use this penis pump size chart below to figure out which diameter we would recommend.

Penis Pump Safety:

When using vacuum penis pumps, one should never proceed to the point where the suction causes pain nor use continuously for more than 10 to 15 minutes. Stop when the penis is only slightly larger than its normal erect size. One of the key safety features of LeLuv® Penis Pump Kits is the included safety release purge valve that allows for a quick release of the vacuum. Any time you want to release the vacuum, you can do so with this included safety valve.

For added safety, LeLuv® recommends a Penis Pump with a vacuum gauge.
