LAPD Two Stage Isolator Cylinder
This amazing bit of kit allows you to both vacuum pump your balls and cock separately and at different levels of pressure.
It is available in 4 sizes, so it's really important that you select the right one to ensure maximum functionality.
Your erect penis should fit from side wall to side wall.
Note: you will either require two pumps to gain different levels of pressure, or the Two Way Pump Connector Hose listed separately.
If you have your own pump/s, you may need one or two couplings. If so then please select below.
