What are the moving barbs called?

I mounted my 120.3 rad in the top of my HAF 932 and now im going to mount the 120.2 rad on the outside panel of the case.

My question is...what are the barbs that allow rotation of the tubes? I dont really wanna have 2 huge tubes with arches going to the back of the case. So I was gonna pick up some of those barbs that move. I know its a bit of a noob question to ask, but hey..gotta do things right...thanks in advance for the help

Sooo would it be easier to get a 90 degree then a regular barb in that? Or get a 45 degree? What would be my best option for this idea?

The 90 degree is neat. It rotates at one place for the angle, and at the knurled part.

(One of many color combos, pick carefully for color)

The 45 only rotates at the knurled part, so not as many bending possibilities. They do have them with built in compression fittings, nice.

In these times of need to finish a build, you should look carefully at a few options, decide carefully, order exactly what you need. Or live with the hobby of watercooling and order a few of each style. Better to spend the extra $$ now than have a rig now and in the future waiting for one stoopid part.

Look closely at my rebuild log and my pumps and rad fittings. I bought just 90's and they are great.

Addiction is fun, as long as it's water cooling.
