The anodized aluminium fittings are supposed to be tight when they are assembled and should not require any tightening when you get them. Unfortunately, 3 of the 4 connections were not properly tightened when they were made. 2 of them leaked a bit. So, I had to go back and tighten them again. So far they are bone dry but I will be checking them frequently to be sure. Other than a couple of wrench marks on the fittings, they should be fine and I don't expect any more issues.

I did confirm with the fine folks at Z1 that end user tightening is not required or even mentioned in the instructions and they noted the minor mishap in my account.

Sooo. If you get one of these kits you may want to check but do not over tighten these connections. Better safe than sorry.
