Yeap, you always have to practice best methods possible, which includes leak testing.


For me, the process of bleeding the air out = vigorous shaking, running upside down, etc = my leak test, hehe.

negative I built 2 water rigs with 2 different sets of parts 3+ years no problems

I ran one rig for 2 years without even changing the water just to see if she would still run. it got nasty after 2 years but ya... it worked flawless


I will only use barb fittings. compression fittings are sketchy IMO

barbs and clamps might not look as clean but are way more secure

i agree, on my second watercooled build now, I only use barbs, first time I used 7/16 hose on 1/2 barbs, now I use 1/2 hose, no problems yet. Make sure you leak test, and have something to secure the hose (I just used zip ties) and you'll be fine.

Going on my second year under water with all compression fittings in 2 separate loops. Had my first leak this past weekend where the swivel on an angled fitting had a leaky seal. Otherwise the actual compression/tube area has been rock solid and can take a fair amount of abuse (tugging etc).

You have to be careful with cheap compression fittings. Its super easy to pull a tube out on accident. I find barbs to be the safest and more secure. Also bitspower compression fittings work well at securing tubes.
post #17 of 22
Compression fittings are more for bling...they have an equal chance of failing vs.clamped barbs if incorrectly tightened/installed.

7/16" tubing over 1/2" barbs will be nearly impossible to pull off (when installed by dipping the hose end in boiling water before pushing all the way on) Add a clamp/worm drive/zip tie and you're gold)

The ultimate in safety, using fittings commonly available in water cooling, would be barbs with worm drive clamps.

Not all barbs are created equal. I have Swiftech, Koolance and Bitspower barbs.

IMO, the Bitspower ones are better, from a leak safety standpoint, than either the Swiftech or Koolance barbs.
They hose barb portion is longer than either one, and they have more ridges for the hose to seal against.
They also have better o-ring retention than either of the other two.

I haven't handled other brands of barbs, so I can't speak for how they compare to the Bitspower ones.

I have some ideas for a build I want to do some day using hydrolic fittings and metal tubing, but that would be massive overkill for a normal build that wasn't going for a particular aesthetic.

Compression fittings ftw. By the time you but quality clamps barbs cost the same. Barbs also seem kind of ghetto by comparison. I am tainted tho to favor compression fittings since I've only used them in all 10 wc builds I've put together. Never had a leak from any of them either.

NO! not at all in my experience.

I've had several leaks using compression fittings on 1/2"ID x 3/4"OD tubing. The only thing I would trust on that tubing size is a worm drive clamp (automotive style), or Koolance Clamps (Spring Clamp). The tubing is just too big for me to effectively get compressions to work with 100% confidence, and zip ties are a bit weak. It's probably entirely user error, but I have NOT had good luck with compression fitting on large tubing.

It depends on the barbs used as well. The Danger Den Fatboys/BP type work pretty well, and short stubby type barbs are less secure.

I find compression fittings work extremely well on smaller tubing like 3/8"ID x 1/2"OD...I love using them on that size, but I HATE using them on large 1/2"X3/4"...PITA and I've leaked way too many times to trust them on that size tubing.
