[Mr. Ivey]

One thing that I was doing when I was setting up some testing cylinders earlier this year I was trying to get rid of the leaking issues with my system. I realized that if I stopped it from one of the adapter fittings, the part that I was adapting to from one of the tanks started leaking. I looked at the adapter fittings and found I was making them oblong, like an oval at the top. If you tighten those brass adapter fittings too tight, you will mess them up. And I know this sounds obvious, but make sure the lines are properly set into the quick connect fittings, it is possible that the lines are not properly seated in them. After you have pushed the line in the quick connect, pull the collar up so that the line is held in secure. As said by ngreen and Andy Brockway, make sure the Norgen is in the right direction. If you look at it from the top, you will notice one end is sticking out further than the others, this is the end you want a pressure guage, the opposite end you want the input pressure, and the other two you can use for running your system. Make sure your pressure sensor is working properly. If your system is not yet in your bot, you can spray a small amount of windex or other window cleaner on the fittings, this will bubble and show you leaks. You can use water, but I have found windex works the best. Hope this helps.
