Large Pump Cylinder

$ 72.99

We carry a variety of acrylic pumping cylinders because we know that genital anatomy varies widely from person to person. At 9 inches long, these cylinders are primarily designed for pumping a penis. Choosing the correct diameter is important and can be done easily utilizing the sizing tool provided in the Sizing tab. This listing is for the cylinders only and does not include the hand pump or the cylinder cushion we recommend using for comfort and increased vacuum seal ability. 

Many people enjoy pumping because they appreciate the look and feel of having a temporarily larger erection, as well as the intense sensations that go along with ultra-engorgement. With practice, you will learn how you like to pump best, but here's a pro-tip: use your pump just after a nice warm bath or shower. While you are warm and relaxed, apply a good deal of silicone lubricant and the penis will be more supple and ready for pumping fun. 

Have fun and be safe! It is very important to go slowly as you begin to pump. Pumping too hard too fast will break capillaries and, in the worse case scenario, break larger blood vessels resulting in serious injury to the erectile tissue. You can get super results utilizing very little vacuum pressure and you will come to know your body and how you respond with practice. It is not recommended to start out using your pump for more than 15 minutes each session and not more than 4 times per week.

To pick out the correct size cylinder, you need to know the circumference of the widest point of your largest erection. For some folks, the widest point will be at the head and for others it will be mid-shaft or even toward the base. Everybody is different! 

To figure out your erect circumference use a piece of non-stretchy yarn, string or a thin strip of fabric to loosely loop around the widest point and mark where the yarn meets. After you have done this lay the yarn out flat on a ruler and measure. Use the chart below (provided by the manufacturer) to choose the correct cylinder size for your body.

This product is made of acrylic plastic.

Acrylic plastic is non-toxic and easy to care for and clean. It’s a hypoallergenic, non-porous material that won’t break down or leach chemicals into the body over time. To clean, use hot water and a body-friendly soap before and after each use. Be sure to allow your cylinder to dry completely before storing.

Acrylic plastic is compatible with all types of lubricant. This material can scratch easily, so keep away from abrasive surfaces, harsh chemical cleaners and do not put it in your dishwasher- doing so will void your warranty.
