Vacuum Adapter for PC Custom-Cooling-Loop

Here i have an Adapter to Vacuum your Custom Loop before Filling or to help fill the loop without Air-Bubbles, it also works great to drain the loop from remaining water.
Testing can also be done with it if you use a splitter.
The Vacuum itself is from Hofer/Aldi and it is really cheap.
