Thick-Walled Cock Cylinder - 6 Sizes
Thick-Walled Cock Cylinder
Over two times thicker than our existing pump cylinders, these Thick-Walled Cylinders require less work and will help you see results faster. The bottom is flame finished, so it’s super comfortable and seals easily with or without a pump cushion. You’ll love watching your meat grow as the pressure in the clear chamber increases.
Made from heavy duty acrylic in the USA so these cylinders are resilient. The thick wall allows the cylinder to be constructed without a flange they are even stronger. Great for newbies and pumping aficionados alike.
Includes a quick connect/disconnect safety valve that maintains the vacuum after you've disconnect the pump.
Available in sizes 1 ½" thru 2 ¾".

Safety & Sizing
Your pump tube should be large enough to allow the tissue of your penis to expand, but not so large that it begins to pull your scrotum into the tube when pumping. Mr. S recommends a tube that leaves roughly a pinky’s width of gap between the outside of your erect penis and the inside wall of the tube.
To find the right size, wrap a string loosely around your cock when hard and measure the string's length. Then use the following guide to help determine the cylinder size you need.
