When paired with the Deluxe Pump, Hush Pump, or Portable Electric Hand Pump, vacuum cylinders offer intense genital stimulation and growth potential. This cylinder has an inner diameter of 1.25" and comes in two lengths, 4" and 5". As an FTM cylinder, it has a wider base than a traditional Pump Cylinder, adding more comfort in use. Made of industrial grade acrylic, it includes a quick connect/disconnect safety valve that maintains the vacuum seal even after you disconnect it from the pump.

Once a cylinder has been put in place and air has been pumped out of it, the pump can be removed, but the cylinder will stay vacuum sealed. This allows the user to keep pressure on a particular spot for extended lengths of time (we recommend 10 minutes at first on a lower pressure setting, eventually up to 30 minutes). When using a pump, always listen to your body and remove the pump if you experience any pain.

Enjoy the extra sensitivity and watch your genitals grow!

This cylinder does not include a hand pump or hose. It fits into the Deluxe Pump, Hush Pump, or Portable Electric Hand Pump, sold separately. Due to health concerns, all sales of cylinders are final, so size carefully before ordering.
