Seems like a bunch of money wasted for something unnecessary? I may have been out of the loop too long but have never heard of anyone using an air leakdown test for water cooling setups. Air is much thinner than water and under pressure it will find leaks that would never exist in a low pressure liquid cooling loop.
If you want to know if your loop will leak, or if any parts are defective, what better way to test that than using the same parts exactly how it will be installed???
Guess I'm finally getting old lol.
The fittings are used to run a pressure test with air. From what I understand, air is more commonly used as it is a better way reproduce what the load would like under pressure.
I am not able to build the true loop out of the case since I will be using PETG. Without know the turns, length, etc, that will not be possible. All the water cooling fittings and tubing are from a build I had years ago, so that was no cost.
