Hardline Compression Fitting tightness

[Paul0305]

Hello all

Im new to the forum so first of all hello

I have had custom water cooling loops in my setup for a long time now but it has always been with soft tubing where I can clamp down the tubes to a really strong connection to my fittings.

Im in the process of building a nice new setup and I am wanting to make the move to hard line as its looks so much nicer.

I have decided to go with the Alphacool Eisazapfen 16mm compression fittings and as I am new to hard line tubing i bought a few test tubes to practice cutting and bending them. The final tubes I want to go with will also be Alpha cool as I thought it best to match manufacturer fittings with tubes but due to stock levels at the moment I purchased some Bitspower None Chamfer PETG 16mm tubes to mess about with.

The one thing I have noticed is that when I fit the tube into the compression fitting I wasnt expecting to be able to pull the tube out quite so easily. It takes a little bit of force but way less than I though it would.

So I wanted to ask, typically how strong do you find the fitting of your hardline tubing is? should it be quiet difficult to dislodge the tube? is it the case that because im trying to fit a bitspower tube to an alphacool compression fitting that there is enough of a sizing difference that im getting a less secure connection?

Thanks all

Thanks everyone

I will put some more work into the bits power tubing round the edges down and see if it improves the strength of the connection

thanks all, I spend a some time today properly rounding the ends of the test tubes I have and wetting the o-rings. the fit is SIGNIFICANTLY improved! its quiet possible I also wasn't properly fitting the tube into the base of the compression fitting properly as the tube has gone from pretty much falling out of the fitting to it now needing a fair bit of force to attempt to remove it.
