I got this fitting awhile back, which was used to cool CPU waterblock.
However I found out yesterday the fitting was broken and caused leak damaging several components in my PC.

Asus Crosshair III: Gone
2 x ATI 5850: Gone

I submitted a support ticket to Jab-tech where I originally bought the fitting to see what actions can be taken.

My recommendation to you all, don't use this fitting.
