A:  Not being able to see your installation location, I would suggest screwing a copper or brass threaded to sweat style adapter fitting that would then allow you to install a sweat style valve. Remove the valve stem assembly before heating the valve to solder the adapter and copper pipe extension to the valve. Also, apply ample Teflon pipe tape to the male threads.

A:  It is possible to tighten both sides of the 3/4 in. x 3 in. MIP Brass Nipple Fitting at once but it is not recommended because it would be difficult to get both sides tight enough to not leak. We recommend tightening the ends one at a time, so another method would be needed to attach the valve to the pipe nipple if the valve cannot rotate.
