Hey guys,
I just purchased a 360 rad, XSPC Black tubing and the matching EK compression fittings becuase I want to watercool my rig in the future.
But I have a problem. if I bend my tubing it simply falls off from the fitting, even if the clamp (that thing that holds the tubing to the fitting) is screwed on. And when I try to pull it out it comes out very easy, and I need to apply the same pressure, no matter if the clamp is screwed or not.
Did I got bad tubing?

what size tubing did you get? I.D. and O.D. tubing comes in two sizes, the inside I.D. and outside O.D. the I.D. will fit on the fitting and the O.D. needs to be the same size for the compression fitting. So if you bought 7/16 x 5/8" tubing you need to buy the same size compression fitting.

Make sure the tubing is pushed all the way down on the barb and the outer fitting is screwed all the way on the get a tight fit.

yes I did buy the same size compression fitting (they were both 16/10cm)..
But I tried running water through them, and there were no leaks (no it was not in a computer because i dont have all the parts yet)

wish I could help you out more but I always use barbs and clamps, never really trusted the compression fittings for that reason.

when you put the collar on the tube before you put the tube on the barb is it a snug/tight fit or is kinda loose?
Is there any way you can take a picture of just the tube on the barb and then with the compression fitting on.
