Fittings

post #1 of 8
Thread Starter 
Some time after I bought my WC stuff (back in 2004) they switched to larger diameter tubing and started selling "fittings" separately from the various water blocks and components.

And man, do they charge extra for them!

So besides choosing the tubing size to use, I have to shop for fittings. Barb or compression or something else? Which brand? Does it really matter? I never cared for "brand" at the hardware store.

My original EXOS has quick-disconnect fittings on the external unit. They were probably sourced from some industrial supplier. Later, Koolance started selling their own line of QD couplings, and they are ghastly expensive!

Odd, I don't see anything like that in the WC catalogs other than the Koolance brand. So are they not common? I used these, in 2007. The current price on the web site comes to $3.85 for a complete mated pair.

These don't auto-shutoff, though. They are just plugs. The idea is that the tubing is long enough that I can pull a component far enough out to clear the case, over a basin, and unplug it. Then I plug the loose ends back together to complete the circuit and wipe down with a paper towel.

Using a British size for the female threads on the blocks and other components makes it hard to just pick them up at the local hardware store in the U.S. But does anybody sell them mail-order that work well and are priced a fraction of what the fancy stuff goes for?

Anyway, I need to choose the fittings for my new loop. What do you suggest?

for the barbs you can pick up 1/2" air hose barbs with a G1/4" thread and they work fine for water cooling systems. they go for about $1 each and normally come made from brass.

otherwise pay for the actual thing, EK make 1/2" barbs that are only $3-4 each and although the Koolance quick disconnects are pretty expensive they are worth the money.

What is the preference: barbs or compression?

Depends really. I've been heavily researching my loop that I'm building for christmas and I'm going with http://www.jab-tech.com/XSPC-G1-4-to...g-pr-4803.html for as many as I can. Other people on here have confirmed that they are actually well built. My vote is for compressions.

If you do decide to get barbs get 7/16 ID tubing and 1/2 inch barbs. Most people on here agree that even if you don't use clamps (please do) it is highly unlikely to slip off.

Compression fittings look better, and is easier than barbs. I'm really glad I went with compression fittings for my first time.

I have gone with compression fittings at a premium, just for "peace of mind" because my nervous system couldn't cope with the possibility of leaks.. it's obvious that with most people going with barbs that they are fine.. but i know i am a bit mental..

i just noticed the other day that MurderMods use barbs and don't even clamp them (omg shriek!) and those PC's are some of the most expensive to buy... so like huh?!?!?!

I swapped from barbs to compression and think it was worth it for the look alone, but I had to use barbs on my gpu so used 1/2" barbs with 3/8" tubing with no clamps but I think I could hang off of it and it wouldn't come off
