If it doesn't leak, it's watertight. If it does leak, then, not good!

Its already been demonstrated earlier in the thread,3/8" is not watertight with 10mm pushfits

Yeah i think I remember that too. Which is why i didn't get any.

By the way what's the difference between 3/8" and 1/2" in terms of Water Cooling? Like is there more pressure with one or other? Does it affect cooling ability? Is one or other harder on the pump? Things like that...

3/8" is around 9.5mm so it's almost identical to 10mm. You will not see a difference in performance. In fact, anything at or above 3/8" will perform pretty much the same. I would personally go with 1/2" tubing if I had lots of tubing and an external rad.

Edit: sorry, I was comparing 3/8" versus 10mm while you were asking about 3/8" versus 1/2".
Still, for internal loop, the tubing size won't matter enough to make a difference. But of course, the bigger tubes will be less restrictive.

The more I look at the 3/8" tube I bought, the more I think its too small, especially in the bends. I think I'll be moving to 1/2".

Question, how do you do your prep with copper pipes?!

Like with rubber you could do it in a sink or something and its easy.
But with Copper, well you cant really move it around too easily.

Do you build it in and do a clean and flush from the case itself?!
Also how would you prepare a loop using copper pipes?

A question for OP, where did you buy the copper pipes? Having a hard time finding a place in EU.

Like I said, if it doesn't leak, it's watertight. If it does, then it's no good. No one is disagreeing here, I think. I just wanted to know what size tubing the guy was using in the pic.
I would not think it would work, but there is a lot of unexplored territory here with different manufacturers and possibly different tolerances/materials in the o ring area. I have yet to see a comprehensive list of push fittings tried with 3/8" tubing. Have you?

Not understanding what you mean. If it's bent properly, the diameter of the pipe isn't changing in the bends.
I thought about 1/2" too, but decided for me the bend radius would be too large for what I will need to do. If you really think you need a lot of flow, or if 1/2" just looks better for you, then go for it.
In the end whatever works best for you.

On another note, I was looking at the Mettleair fittings last night and noticed there is a provision for tightening internally with a hex , or allen wrench as we call them in US.

Wait a minute....those Phobya fittings work with 3/8" tubing??

The copper one is 10mm OD and the chrome one is 3/8" OD. I was playing around with sizes to experience them for myself. One thing I noticed t hough after I had the 3/8" pipe plated the MettleAir fitting is having a hard time bite into it. It's now easier to pull it off even without pushing the blue lock compared to when it was just a bare copper pipe.
