Compression fittings or barbs?

post #1 of 13
Thread Starter 
So after a week of research, I've finally got a list of the parts I'm gonna get for a liquid cooling kit for my desktop.

However, I've come across a slight dilemma, I've been looking at standard barbs to which you connect the tubes to, along with jubilee clips to hold it secure.
Or.
I could go for compression fittings which look a lot nicer.
A friend of mine who works as a plumber has mentioned that I should just go for the barbs and clips as he has seen that most leakages in pipework happens through the compression fittings.

What are your opinions guys?

Barb fittings require no maintenance and are possibly more trusting for no leak.. It's a pain in the ass to try and pull them off the tubing . I've always just cut them off..

Compression fittings require some maintenance for the first while as the tubing gets a little loose requiring the fittings to be tightened for the first few weeks.. You can slide them off the tubing though when you need to.

Barb fittings are more hassle free until you dismantle the loop, in my opinion they are less prone to leakages as well. Compression fittings look better but require tightening a couple of times in the first month due to the tubing shrinking. I prefer compression fittings because I like the look of them and I don't mind the maintenance but it's up to you smile.gif

You'll be fine with either, in regards to leaks (follow advice from above posters). Honestly though, for aesthetics it's more dependent on whether or not you use angled fittings (45 and 90s). Angled fittings will cut down on the tubing, so you won't have huge loops covering up your components. Again, speaking only of aesthetics the order, from worst to best is:
1) Straight barb fittings
2) Straight compression fittings
3) Angled barb fittings
4) Angled compression fittings

So some maintenance after a while, got ya.
Do I have to do this continuously or can I stop at some point?
oh also, what kind of maintenance do I actually have to do once I've tested the loop for leaks and what not and installed it into the desktop.
I didn't think i'd need to purge it if I'm using an actual coolant rather than concentrate diluted in water.

I have used compression and barbs and I think I prefer barbs a little more. They seem less likely to leak and compression always make me a little paranoid that they are slipping off even though I know they are tight.

luckily I have the benefit of a full tower to work with in terms of space, but yeah, my list consists primarily of 60 and 90 degree barbs if I chose to go with barbs.
Probably will try to keep tubing to a minimum as I'd like to cool the ram as pointless as it may be. but I'd probably never do that as I only really want to do that as a cosmetic purpose.
I like looking through the window pane on my desktop biggrin.gif

The tubing shrinks slightly as it gets warm, if you're using barb fittings this is fine but you'll need to tighten the compression fittings manually. You only need to do this for the first 3-4 weeks until the tubing stops shrinking.
If you do your loop properly and spend time on it you don't really need to do too much regular maintenance, many people flush out their loop every 3 months but it's not really necessary. Coolant these days has a life of about 2-3 years.
If you do the following the only thing you'll need to do is drain and clean your loop every 9 months or so.
  • Don't mix metals
  • Use good quality coolant (don't use distilled water!)
  • Make sure you clean your components thoroughly before putting them in (flush them out with distilled water)
  • Use good quality components

If you do the following the only thing you'll need to do is drain and clean your loop every 18 months or so.
  • Don't mix metals
  • Use good quality coolant (don't use distilled water!)
  • Make sure you clean your components thoroughly before putting them in (flush them out with distilled water)
  • Use good quality components

gotcha, I'll stick with the barbs then as its less hassle free, and I don't want to be on edge thinking my desktop could be shorted out at any point in time.
I do intend to fit the loop in first to get all the measurements for the tubing. Then detach the system so I can test for leaks else where from the desktop. I'll be testing it with diluted water. Will that be sufficient for flushing it?
