These fittings performed perfectly and I had no problem achieving a water tight seal, despite this being my first experience with water cooling. The only issue I had was with screwing the fitting body into my components. The threads were extremely sharp and I cut my fingers quite a bit when tightening them down before I realized what was happening. It not like I was cranking down on them in the first place, but being more careful and using rubber gloves was enough to avoid further issues. Perhaps this is something a more experienced PC builder would have known to watch out for, but this seems like something that could be easily fixed in the manufacturing process. Overall though I'm extremely satisfied with the result and there were barely any cosmetic defects relative to amount of the discount.
