Pipe bending 101 - Page 48

post #471 of 2160
I did a two hour leak test using these fittings:
http://www.overclock.net/t/1280153/pipe-bending-101/440_20#post_19288846

Test set up was an old Rasa block with these push fittings installed, copper tubing, with the copper tubing linked to an X20 pump with normal tubing.
Note the cat food snack on the counter. Yes, water cooling has drained my bank but one must push on. tongue.gif


Of course this isn't the most powerful pump, but at least it provided some baseline testing.

End result is no leaks after two hours.

During the testing I would periodically try to rotate the tubing within the fittings to simulate a stress condition, and still no leaks.

At a price of about $16 for 10 fittings this would seem a great deal, provided the fittings hold up in the long run.
Please note these fittings are sold for plastic tubing, and are not sold or recommended for liquids, although use with liquids was not specifically listed to be avoided.

Thanks man, I was gonna go and test mine but you did a great job. Shipping from Canada was very slow for these fittings. The rest of mine just arrived. I will be using these MettleAir fittings for my loop although they will be hidden, but they will serve the purpose.

You guys are so brave, lol. I fear the long run effects. Who knows how they hold up after 6 months?

I meant to post this awhile back but I know some people have looked into the Camozzi fittings. I emailed them about using their products with metal tubing and here is the response:
Quote:
Thanks for your inquiry. I would like first explain a couple of technical detail about our fittings.

The part # selected P6510 06-04 is a push to connect fitting as you stated. The important factor to be aware of is that these fittings are pneumatic fittings. This means that according to ISO test followed during production and testing, these fittings can have a leak rate of up to 1cc/min.
That said, it is also true that we sell our fittings in low pressure lube application and even in misting systems, but all these applications are tested and approved by the customer.
In your case, without knowing exactly where the fittings would be installed we would not to be responsible for any damages that occur to the computer.

The second technical issue is that the stainless tube would work, but the face of the tube would have to be square, with chamfered edged to prevent cuts or tears in the inner tube o-ring. Also the tube would have to have a score in it, an undercut, so that the teeth on our collet would have a surface to grab on. These collets are usually designed to work on soft plastic (nylon and PU) tubing, by grabbing the softer OD, but with metal tube the surface is too hard. The design just to give you a visual would have to be similar to our models 6800 or 6950. Here is the link to our catalogue:
http://www.camozzi-usa.com/documents/fittings/fittings/nickel-plated-brass-push-in-fittings.pdf


I hope the above explanation is clear.

Let me know if you have any other questions.

Regards,

XXXXXXX

So for the sake of just being safe I went with the Koolance fittings. Nice to see your results Mandrix! Glad those are working out.

Well you can't be sure that any of a number of water cooling fittings won't leak. I had a Bitspower rotary leak so who knows?
But I couldn't fault anyone for not using any of the pneumatic fittings.
The problem is that most of the water cooling fittings in general are way overpriced.

Koolance doesn't make any fittings for other than metric tubing , do they?

Wow the price went way up on these for some reason too.

OK, so you are actually using 1/2" OD pipe? I want to verify this.
Could be that little bit of difference is taken up by the way the ferrule compresses to the pipe.

Also I put a call into PPC-s about the 3/8" fittings and they are going to check with Koolance to make sure they will work with 3/8"

I'm hoping the fittings I bought will work out, of course, but in the short term I may run the Koolance fittings in the motherboard area until I'm sure the mettleair fittings aren't going to leak on me.

On another note, anyone have any tips for straightening out coiled tubing?
I thought about a little heat but I'm thinking that might anneal/harden the tubing a little which I don't want.......most of my experience with copper tubing is either flared ends or brazed on fittings and straight "nice looking" tubing wasn't really a consideration for my home lp gas lines.
post #480 of 2160
What I had thought of doing is putting it on the table and between 2 pieces of lumber and then just run my finger while pushing down along the top.

Either that or I'd try a pair of 1x 6's clamped over the piping with a hole just big enough for the pipe lined with fabric and run that along the line (or pull the line through).
