This is a Penis Cylinder with additional separate chambers for your cock and balls. It has different levels of vacuum pressure that yank the penis up and out, and pull the balls away from the body. This special cylinder is made with three chambers and two valves. The most important measurement is for the penis chamber.

In order for this cylinder to work to its fullest potential, you must be able to fill the penis chamber from side wall to side wall. After you fill the penis chamber, a second valve allows for adjusting the pressure in the chamber filled with the balls. When pressure is decreased in the ball chamber, it yanks the balls forward, pulling them away from the body. Measure around the balls and penis when hard.

This cylinder is designed to be used for penis pumping as intense erotic massage, or for penis extension. It comes with an Air Pressure Valve designed to be used with our Basic or Deluxe Brass Hand Pump.

Before we get into discussing the joys of penis pumping and the exceptional quality of this new line of pumping products, we want to say this first: Proceed slowly and with care.

Excessive pumping can lead to discomfort and injury. When using pumps such as these, never proceed to the point where the suction causes pain. Stop when the penis is only slightly larger than its normal erect size. Be sure to read all the directions and warnings, and be conservative and cautious in using these devices.

When pumping, it is strongly suggested to not pump for more than 10 minutes a day. These new penis cylinders are hand crafted of the finest space-age polymers. Each crystal clear cylinder is built for comfort and the best vacuum seal without the use of awkward rubber gaskets. All expansion tubes include a quick connect/disconnect safety release valve that allows for disconnection from the expansion tube while maintaining the exact pressure you have chosen.

How does cock pumping work? The penis is well lubricated and inserted into the tube. The pump is attached via the safety quick release airlock attachment. Upon pumping, a vacuum is created. Penis enlargement happens as your penis grows to maximum dimensions inside the tube. While overzealous vacuum pumping does carry some risks, when done carefully, it is a safe way to achieve mild penis enlargement. The most frequent problem is pumping the cock too hard and fast, stressing the penis. Too strong a vacuum can cause temporary bruising of the penis, water blisters, red pinpricks, etc.

Go slowly and increase the vacuum gradually over a long period of time. Medical Doctors have been using vacuum pumps to treat impotence for years. If done carefully, pumping is safer than surgical alternatives to penis enlargement. After long pumping sessions, most people get greater increases in width than in length.

It's difficult to predict how much of an increase in length will occur, but it's possible, while in the cylinder, to gain as much as 2 inches or more in length. Generally the increases in girth will be larger, and longer lasting. Penis width is increased using wider cylinders. If you're more concerned about getting increases in length it is suggested that you buy a narrow cylinder. Your penis will get more of a pull in length in a long narrow cylinder.

Find Your Length: Optimum penis cylinder length is 2-3 inches longer than the maximum length of your erect penis. (Lay a ruler on top of the penis with the base nestled snugly against the point where the penis shaft meets the body.)

Find Your Diameter: Penis enlargement cylinders are sized using the circumference (the distance around) the penis when erect. To measure the erect penis, wrap a string, a shoelace, or dental floss loosely around the thickest part of the penis when erect. (Usually this is very near the base, but some men find the area near the glans (just below the head) to be thicker. Mark the string where it comes together, lay the string out flat next to a ruler and measure the distance between the markings. This measurement is your penis circumference.

The diameter of the opening is 3¼”. The top and bottom diameter of the chamber for the balls is 5¼”. The circumference of the chamber for the balls is 14¼”. The length of the chamber for the balls is 1¼” on the short side, and 6½” on the long side. The penis/shaft chamber is 7½” in length and has a circumference of 7¼”. The diameter of the penis/shaft chamber is 2”.
