Each cylinder is hand crafted and made of the finest, industrial strength crystal clear acrylics. The cylinders are tapered toward the top to match the natural anatomy of your penis for maximum comfort. No gaskets are required. Each cylinder contains a state-of-the-art air valve which allows for quick and easy disconnection from the pump while maintaining pressure within the cylinder.

After using penis filled tube and going to next size. The 1.75 is now to small as girth has increased. With the increase it has increased the sensitivity during oral sex.
Great tube at a great price! already seeing gains in length and my girth. using a good lube is highly recommended for each pump session.
Great cylinder for the price. Have not had any problems with suction or seal yet.
I am very pleased with this cylinder! The cylinder I ordered through Vacu-tech was a little too big for me, and I didn’t have the money to buy a 1/4-inch smaller size (their asking price was about 80 dollars at the time). The price alone is worth it, and it is a very durable product! I have been using it for about 20-40 minutes a day for two weeks with no noticeable durability problems.
I am giving this product a 4-star because the top nozzle does not properly fit with the pump I already have from vacu-tech, and I am not willing to shell out another 40-50 dollars for the size matters pump. The connection difference only causes the vacu-tech to disconnect on its own from time-to-time. Also, the cylinder width narrows, or becomes shorter as you move from the base to the end, and this doesn’t work as well; I find that the head of my member presses against the sides of the narrower glass because of this, and circulation is lost a bit.
