LA Pump Two Stage Isolator Cylinder

LA Pump offers a unique and varied assortment for advanced pumping, unseen elsewhere in the world. The LA Pump Two Stage Isolator Cylinder is designed with separate chambers for your penis and balls, with different levels of vacuum pressure, pulling your penis up and out, and pulling your testicles away from the body.

This special cylinder is made with three chambers and two valves. The most important measurement is for the penis chamber. In order for this cylinder to work to its fullest, you must be able to fill the penis chamber from side wall to side wall.

After you fill the penis chamber, a second valve allows for adjusting of pressure in the chamber filled with your testicles. With the increase of pressure in the testicle chamber, your testicles are pulled forward, away from the body.

Please note: This cylinder will not fit if you are less than 7" in total erect length and have a penis and ball circumference of 10" or above.

Also, the silicone cylinder cushion does not fit on this cylinder. The opening for this cylinder is always 3" in diameter. This cylinder is best suited for those with 7.5" in erect length and above. 

How to determine your size

Measure the diameter of the shaft of your penis after pumping with a regular cylinder. Choose the same diameter or one size smaller for your Two Stage Isolator Cylinder because you want the shaft to fill the shaft chamber wall to wall.
