Using 3/8" tubing on secondary loop...

[virtualrain]

Thanks Marci... I was planning on using the Koolance compression fittings for 3/8" as they also have some matching 1/2" fittings I can use on my CPU loop. The 1/2" fittings are designed for 1/2" ID and 3/4" OD and are way to big to use on most blocks without the locking rings interferring... which is why I want to go with the 3/8" on the secondary loop.

Looking at the tubing that Koolance sells, it appears it is 3/8 ID and 14mm (0.55inch) OD so it would have 2mm walls. I guess I may have to buy their tubing as this sounds like odd specs. Does anyone else make tubing with those wall specs?
