Koolance QD3-FS13X19-BK QD3 Female Quick Disconnect No-Spill Coupling, Compression for 13mm x 19mm (1/2in x 3/4in) *Black*

If you have the cash to spare, these are a great way to streamline your liquid cooling design. It is incredibly simple to repair and replace tubing. You don't have to purge or drain your system to isolate a pump or radiator. For major components, I strongly suggest these. The compression fittings are excellent and simple to install, thanks to the large, easily turned nuts that can be tightened with finger compression. However, they ARE bulky. br>br> On any build, expect a two-inch flex loss. They're great for pumps and radiators, but you'd have a hard time getting one to fit a CPU to VGA connection, for example. br>br>Be sure to order the CORRECT QD and the CORRECT PIPE FITTING SIZE when ordering. I ended up with six QD 4s when I needed three, and I had to pay for replacements before shipping the originals back.

I enjoy not having to drane the water when disconnecting my GPUs.
