Push in fittings, good or bad?
 

Want to get some informed opinions on the push in water fittings from liquid cool. http://www.liquidcool.org/main.php?z...ion=10&group=1

They look similar to the fittings you would find on a dishwasher or ice maker. Anyone know if these are reliable? Thanks in advance.

I haven't seen a negative comment about them, but that doesn't mean they are really good either. Knowing the owner, he won't sell crap

if 'LiquidCool' posts in this thread, he will be able to tell you, he owns the site

McMaster Carr has the same thing and I've used them in Air Pnuematic systems with no problems, just make sure you read about the proper tubing at McMaster Carr and you'll be fine.

Never tried them, but I really like the idea.

Hey liquidcool
 

Actually I just took a look at them and was wondering, why not 5/8 OD? Isn't all 1/2inch tubing 5/8 OD?

Thanks for all the responses.

Re: Hey liquidcool
 

No you can get thicker stuff, I have seen 1/2" ID tubing that is 3/4" OD or more.

The problem with push in fittings is that they grab the hose and scar it. You can only use harder hoses with it. NO SILICONE. other than that they work great. When you disconect your system it just takes a few seconds to unhook all the hoses and there is not much leaking.

Oh, one other downside the mechanism that is used to make a seal when you unhook your tubes will restrict flow somewhat.

webmedic I think you're referring to quick-disconnect fittings, not push-in or compression fittings.

Actually I was reffering to a product that did both because thats what I had been looking into myself. However you can get the push in fitting without them being quickdisconect. The pushin fittings still require a stiffer tubing than silicone because of the way they grab the tubing to create a seal.

I ordered those fittings from liquidcool w/ some 3/8"id-1/2"od vinyl tubing from home depot. If you put any lateral pressure on the tube a small drip will appear. No problem if all ur hoses run straight but if you have a loop or a half loop they may drip.

This is just my personal experience though. On a side note it was very pleasureable doing business with the company, and I will prolly use them on another project.

that's because you used the wrong hose, if you do the research and buy the correct hose to suit your application from McMaster Carr then you wont have leaks ;)

I've used push fit connectors from the Festo range in my system, bought locally and rated at 10 bar air. As said the tube needs to be stiffer nylon type which gets very non compliant as the tube size gets bigger. The two items in my system, (HDD waterblock & PSU waterblock), share the same loop and don't require high flow rates. The tube is 6mm OD about 4.5mm ID is fairly compliant, easy to route and work just fine.

Actually they dont restrict flow at all :) unless your going down to 1/4"NPT or smaller tubing.

AND NOW! you can use silicone! I found a place that has small sleeves that insert into the tubing and stiffen it up. It's still thinner than a barb so your stil getting better flow.

Also if anybody has been trying to get me, my HD has died and I'm waiting on my replacement. I'm at work now, but I'm just harder to reach...

Yes the part that I was reffering to restriscting flow was the quick discinnect fittings. The press in fittings do not restict flow in any way.

OK, that PSU water block just gives me the willy's. I couldn't trust water cooling that far :eek:

thats cool LC, most of us like to use silicone of course.


240v right next to your water cooling setup, no thanks. most psu fans are fairly quiet anyway, and wouldn't be intrusive compared to your hdd's, radiator fan, etc

I researched this PSU water-cooling for almost 6 months before doing it and so far it's working superbly & safe. The Block has all the mosfets mounted to it and is all copper soldered construction air pressure tested to 5 bar, (70 PSI). Push fittings were exited out the side so no pipes would go inside the PSU incase of drips. To me the PSU fan(s) even at 5v were intrusive and the project is about total Performace PC silence. HDD's are 2x new Seagate barracuda IV's with fluid drive motor and ARE virtually silent. My cooling system also has no fans or rads, Zero fans means Zero fans and with my open PC about three feet away in a silent room with no background sounds the only thing I can hear if I really listen is the very very faint buzz of my cathode ray tube. :)

Liquid:

Those sleeves are almost impossible to find for 1/2ID tube. If you have some, I'd be VERY interested.

just use 5/8" barbs with 1/2" silicon tubing. no restrictions.

blade, you have that big thing in your lawn don't you?

Yes this 8 foot down under:-

I've got 40 at the house if you want some, I can get as many as you want now that I know where to get them. Unfortunately they charge an arm and a leg :( $.25 a piece. Once I get to order a bunch I can get them down to $.20... But they work freaking GREAT. I'm putting together a system for my boss (dual celerys) and they grip as good as hard tubing!

What size silicone tubing are you using with that?

Bladerunner, that pic of the subterranean cooling tank made me bust a gut laughing. I was wondering how you were cooling your water without fans or rads.

My wife thinks i'm obsessive about my computers. She should see some of you guys :D
