MityVac HydroVac Penis Pump Systems


After 15 years of research and development with the veterans of penis enlargement, MOS is proud to announce the MityVac HydroVac Penis Pump system.

Whether you are just enlarging the penis or want to do full package pumping with your penis and testicles, the MityVac HydroVac offers a wide range of diameters to accommodate your pumping goals by air vacuum pumping or hydro water pumping.

For many decades, penis pumping has been the most effective way to enlarge the girth of your penis and elongate it. Short term penis pumping achieves immediate penis enlargement that lasts for hours. Many porn actors pump before shooting a scene to perform with their maximum penis size. Long term use of penis pumping results in permanent penis gains.  

Our systems are designed so you can begin with a starter pump set and once you out-grow your starter system all you have to do is upgrade to a  new larger cylinder to save money and keep building penis size.

Our MityVacs come with Silisleev Silicone Penis Sleeves for Fluid Reduction, Hydro Water Trap, Pelvic Silicone Comfort Seal and a Discrete Carry Case.

  • Six hydro & vacuum cylinder diameter sizes to choose, ranging from 1.75" (45mm) up to 3.5" (89mm)
  • Handcrafted Lab Grade acrylic vacuum cylinders with a flange for comfort.  Internal dimensions 9.25" (254mm) long with 4mm thick walls and precise measurements in inches and millimeters to track penis gains.
  • High quality quick connect fittings on the cylinder and vac-lines to allow pressure to be maintained and quickly change from hydro to air without the vacuum pump needing to be attached to the vacuum cylinder.
  • Hydro water trap for Hydro Pumping with water
  • High quality ergonomic nylon body vacuum pump and precise vacuum gauge.*
  • Vacuum range: 0-28.9 Hg, 0-760 mmHg, with a vacuum release trigger for safety
