Time to journey down water cooling...

It's not trial and error - it's reading instructions and advice.

7/16 is 7/16
1/2 is 1/2

7/16 (which is smaller than 1/2 [8/16]) and will fit very snugly on 1/2 barbs.
BUT compression fitting are different - read the sticky and please do some research before you get water all over your pc.
It's not differcult or elitist but you need to be careful and know what you are doing.

Edit: Oh and compression fitting are a pita if you get your tubing even slightly wrong.
It's the reason people don't recoment them to first time users.

Aye, don't be too hard on him, it was partly my fault he got the wrong size fittings as I wasn't aware of the compression fittings issue, having always used barbs :(

Building a w/c loop is a daunting task but I'm sure he'll get there.
 
The comps are fine to use but hes just going to have to buy some more tubing thats the right size. Can you give a link to the exact ones you bought?

Thank you but just to clarify I have been researching and research over the last few months on water cooling...the whole barb, fittings, tubing side of things is what confuses me the most, hence why I have been closely talking to reflux about these and he has assured me of what I need, but as I said I got confused over the tube sizes to work with the compression fittings...I have never done water cooling before purely for the fact I could get things wrong...I may have bought the wrong size tubing but at least it means if things work out, i can use the tubing on one of my other machines and water cool that using 1/2" barbs...

In the meantime I will purchase 1/2" tubing to with the 1/2" compression fittings I have...if anyone has any objections please say so now otherwise I thank you all with your help and suggestions :D

To the OP, in case you don't grasp what is being said, if you look at the last of your pictures, the "lose part" is the fitting you have on the end of the that tube. That fitting should first be on the other way round, and second should be able to freely slide up and down the tube. Clearly the OD of the tube is much too big for that.

hence why I posted the pics for all to see what i was talking about...i realised this when i put the tubing to the fitting...now i know what exact size tubing I need...

Hold, make sure you get 1/2" OD tubing, which is usually 3/8" ID tubing, if you are sure your comp fittings are design for 1/2" OD tube. I won't mention 10/8mm tube. Oops I just have. Most people when they refer to tubing will say 1/2" or 3/8" without specifying they usually mean the ID.

Got ya...1/2" OD...so ignore the last post then lol...the compressions are:

http://www.overclockers.co.uk/showproduct.php?prodid=WC-012-FO&groupid=701&catid=193&subcat=1049

and they state they are 3/8"ID and 1/2"...
 
To be absolutely sure take a ruler to that lose fitting in the last picture and measure the diameter of the hole. If it is greater then 12.7mm then it will at least slide up and down the tube you specify above. I have to take your word for it the compression fittings you have are designed for 1/2" OD tube as I have no experience of them myself, and the common ones I have seen have been designed for 10mm OD 8mm ID tube.

Measured and its definitely smaller than 12.7mm so the tubing I bought with it was definitely the wrong size...I have found the right tubing on a competitor site (since OcUK seem to be going out of stock on jsut about everything watercooling) so I will buy them there...
 
my slow edit from before.
Looks like you have tube that is 7/16 ID 5/8 OD
but compression fitting that need 3/8 ID and 1/2 OD - you need to buy some 3/8 tube with 1/16 walls not available here. 3/8 ID + 1/16 wall + 1/16 wall = 1/2 OD
Clearflex 60 and the high flex XSPC stuff is surposed to work but you will get kinks :( as the walls are 1/8 thick giveing 5/8 OD
Masterkleer Tygon and Feser all make the stuff.

ID inside diameter - OD outside diameter

Sorry for sounding harsh.

tbh I don't know why the shop sells the fitting and no tube to fit them :confused:

It's ok...all this watercooling lark is really confusing when one doesn't know what is needed...but at least with some guidance I will get there eventually...I dont expect it to run smoothly nor do I want to do it quickly...hence the lengthy buying process and making sure I get all the bits right...I expected hiccups along the way and I am sure there will be more to come...:D

The hole is smaller than 12.7mm? So it must be designed for 10/8 tube? You're getting me confused now. To be absolutely sure, looking at the last picture in your set above, the fitting which is on the tube, the diamater of the hole facing us in the picture, is less then 12.7mm (1/2")? What exact diameter is that hole?

lol...no...sorry it is 1/2" exactly...no bigger no smaller...
 
The common compression fittings do seem to be 10/8 mm rather than imperial.

Barbs are pointy things you push the tube over, so the inner diameter needs to match.
Compression fittings bite down on the outside of the tube, so the outer diameter has to match the fitting.

Imperial measurements confuse me, so I've gone with 10mm outer, 8mm inner with appropriate compression fittings. All good fun, at least compressions don't seem to leak
