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.
