Are any tool to tighten besides pipe wrenches ?

The "real world answer" is, in a pressurized water supply line you may need to use a channel lock pliers to tweak the hand-tightened fitting. That was my experience with the 1" fitting on a 60 psi water line. I'm talking less than and extra quarter turn, however.
