We have had a lot of fittings over the years and we can tell you that some manufacturers fitting are not relay fit for purpose and some are spot on, same goes for tubing. There fitting from the same batch can be any ware up to 0.4mm out, take this into account some tubing can be up to .5mm out then you have up to a 0.9mm tolerance between fittings and tubing. Our tolerance is some thing like 0.2mm (im not at work its Sunday but will check it once i get back). Its virtualy impossible to get it any lower due to the way tubing is manufactured and if we wish to get it lower the cost would increase by more than 4x its factor due to wastage.
I understand its difficult to QC things from afar say the company is based in USA , they ship from there OEM manufacturer in China and they have to trust the company in china is doing the QC they need. All fittings should have a tolerance rating and this should be published in there sales documentation for web sites to re produce. Now taking a quick look though oem manufacturer web sites they produce this information, take a look though manufacturers web sites they do not show this information and this information is not passed onto web retailers and shops. I have just checked our web site and we have done the same how ever i will rectify this and get this information up on our site asap.
More transparency is needed in PC liquid cooling market and you can only fix this by approaching manufacturers / producers and asking them to show the information you need, so you can make an informed decision based on facts. If those facts they produce on there sites do not meet the end product then you can refute said facts and point out mistakes and the manufacturers then can work on them. It is all ways best to approach the manufacturer / producer directly and speak to them rather then just posting on the web as manufacturers need to gather this information and fix any issues that may appear.
In the mean time there is a simple cheap fix. If your fitting and tubing slide off each other, you can slip in a small 0-ring to add more compression on the outer wall of the tube. this will fix the problem at your end. Don't forget though some fittings are metric measurements and some are imperial measurements so you may all ways find a discrepancy between fitting and tubing if you don't match them up correctly.
