With the Pumpin gum Ball it is now no problem to change the liquids. This little helper removes most of the old liquid residues from a system. The Pumpin gum Ball creates pressure in the system and removes the drops from all corners by a constant pumping.

On one side there is a 1/4" female thread. The circuit is separated at any point by unscrewing a connection in the system and can thus be screwed into the Pumpin gum ball. If you use a fillport it is easier and you can connect the ball there.

Hint:
To empty your system as completely as possible it is important that you pump slowly and evenly but steadily. Too fast and too violent pumping can have an adverse effect.
