The second item is showing a water piece, but the item being sold is just an adapter for a water piece ("glass not included").
The first item is a very good adapter and will let you hook Mighty up to a water piece having 14mm female or 18mm female inlet.

And so, using a wpa (like the delta3d in you first link0 and adding a simple j-hook can be found to suit the condition you describe. Something like this;

@Maddmoe, it's really bizarre, they are a big and well established concern. I believe there may be a way to contact S&B in Germany to tell them the guys in US branch are fucking up. Will look for that.
