Are these fittings right or am I doing something wrong?

[RobCBR]

Hi just got these water cooling parts in and the fittings i got seem to slide off so easily when i gently pull on them. I know with normal tubing that compression fittings are almost near impossible to pull out, but with these fittings are made for these types of tubing right? Sorry its my first hardline build and I was hoping anyone with any experience could help.

The parts I got are:

They should be compatible. If they are being removed fairly easy, I'd say double check your O-rings in the fittings and make sure you are tightening everything down good. If you are still having issues, I'd suggest contacting Monsoon for their suggestions. If you have any soft tubing laying around, try that and see if it feels different. You could have just got a bad batch of tubing.
