Another n00b question - Tubing/barbs

post #1 of 8
Thread Starter 
I am a first timer in the watercooling department so go easy on me! LOL!

I feel a bit dumb asking though. So I am compiling a bunch of components for my first W/C build. These components I assume don't come with barbs I assume. So if/when I buy the barbs, what are the size of the barbs dependent on? And lets say I get a 1/2 barb. Do I get a 1/2 ID tubing or should some of the tubing be smaller to make it tighter? Or is it possible?

You either want to match the tubing size with the fitting size, or, in the case of 1/2" barbs, you can use 7/16" tubing which will make a very tight seal. If you use 1/2" barbs and 7/16" tubing, you won't need to use clamps. With any other scenario, you want to ensure your fitting size matches your tubing size, and that you are using clamps.

So I wouldn't use any clamps regardless? I thought that was like a requirement.

Nope, you need clamps unless you use 1/2" barbs and 7/16" tubing, as then the barbs are big enough to hold without clamps.

Nope, you can get away without using any sort of clamps if the tubing size is one smaller than the barb. Most commonly people use 7/16" ID Tubing on 1/2" Barbs, but you can also use 3/8" Tubing on 7/16" Barbs.

The only caveat I'd add is that if there are fairly tight bend in the hose, and/or you're using short barbs--use hose clamps. For $1/each for real-metal hose clamps, they're a cheap way of not worrying about frying your $1000 box of computer hardware...because you bumped your radiator, pulling the hose slightly off the barb-dripping coolant onto your GTX595.

Way to put it in perspective my man. Nicely put. LOL! I'm making sure this doesn't happen.
