How many wraps of Teflon tape around nipples that need to point in one direction?
I was taught to never exceed 3 wraps of Teflon tape, because all it is there for is to lubricate the threads and fill in the microscopic gaps between the tapered threads. Too much tape and you interfere with the threads meshing to hold pressure, so you end u relying on the tape to do that, and it was not designed for that purpose. If you read the instructions that come with the tape, it probably says that.
