jbarker4682 Posted October 20, 2019 Share Posted October 20, 2019 Hello all... I have the 14mm OD PMMA tubing from Corsair along with various XF Hardline 14mm OD fittings like this one: https://www.corsair.com/us/en/Categories/Products/Custom-Cooling/Fittings/hydro-x-fitting-config/p/CX-9052007-WW However, when I try to push the end of the tube into the fitting, it doesn't go in vey far, or is crooked, and even after tightening the O-Ring down, the fitting comes off with very little effort... What am I doing wrong? Link to comment Share on other sites More sharing options...
skyteam78 Posted October 20, 2019 Share Posted October 20, 2019 Hi. It is important to prepare tubing before putting it into the fitting. Did you make chamfer on outer diameter of tubing after cutting it? Link to comment Share on other sites More sharing options...
Nazgul Posted October 21, 2019 Share Posted October 21, 2019 Yep! Seems like you need the deburring tool and smooth out those inner and outer edges. Also, you do need to push a little hard, it won't go in easy, I thought I was going to break the o-ring when I pushed the tubing but no, nothing broke. Push till you can't push anymore and just to make sure, measure from where the stop of the inside of the fitting is, to the edge of where the nut sits, I think it's like 1/4 of an inch.......I may be off. Or half? But definitely, the tubing should not come off after tightening it down. Link to comment Share on other sites More sharing options...
Zotty Posted October 21, 2019 Share Posted October 21, 2019 (edited) I use one of these on my PMMA tubing. generally called a reaming tool.. it will round off the inside and outside edges can also be done with a fine grit sand paper this was done with a Reaming Tool like above http://i.imgur.com/3ynnTdZl.jpg the art to is it is being gentle.. no need to be apply huge amounts of force when using the tool Edited October 21, 2019 by Zotty Link to comment Share on other sites More sharing options...

With XF Hardline fittings there is 6mm from stop to the edge of fitting (without the compression ring). Link to comment Share on other sites More sharing options...

jbarker4682 Posted October 21, 2019 Author Share Posted October 21, 2019 Thanks everyone for the feedback... I was finally able to get the tubing to seat properly and now the fitting does not come off anymore... Link to comment Share on other sites More sharing options...
