Tighten pipe nipple without damaging threads... No hex center
I need to use a pipe nipple to join a 3/4" female thread from a pressure tank T to a 3/4" female stop valve.
The nipple is only 2" long and has no hex center. If I use a pipe wrench, won't it damage the threads?

The jaws of a 6" pipe wrench should be narrow enough to fit between the threads on each end. However in this case I sometimes just tighten the nipple in by hand as much as possible, thread the valve on then use a wrench on the valve to tighten both at the same time. One will become tight first and stop turning. Then you continue to turn the valve till the other is tight be it valve or nipple.
A third possibility is an internal pipe wrench to tighten the nipple but I never really found the need to use one. One of the other two methods worked well for me.

Use Rectorseal pipe thread sealant rather than teflon tape for a better connection and use Ray's suggestion in using the valve as a tightening point.
