I 've built a few custom water cooling with mainly a soft tubing and compression fittings. I am in the process of building a new PC and I am going use petg tubing. Do you hand tight the fittings or must use a tool to tighten it. I've seen a couple youtube videos showing the person only hand tight. I just want to know and make I Understand how it done. Tell me how are you guys doing it. Of course I ordered hard tube fittings already.
