I have several 3/4" and 1/2" stainless steel pipe nipples that cannot be fully tightened with stainless steel elbows, couplers, etc. That means I need to find a plumber who can thread in the right size nipples.

I ordered everything together in multiple orders: 3 x 4" x 1/2" NPT and 2 x 2" x 1/2" NPT. Unfortunately, they are cut inconsistently, which takes a lot of time to fix issues that shouldn't be there. Just to give an example, with the same female threat I was able to hand rotate one about 3 turns and the other only half a turn. When cut well they work well, but I don't like playing the lottery. that I'll be "good".
