I'm assuming that I need either this... Full-Thread Pipe Nipple.
1/2" NPT, fully threaded the entire length. 1.125" long.
or this1.5" Pipe Nipple.
1/2" NPT, this nipple is 1.5" long
to connect the ball valve to the keg coupling, right?
How much is that valve? It may look fancy, but I say save your money and get a simple ball valve that works just as well. Maybe even better, as it has less parts to clean that may possibly harbor infection.
Regardless of which valve you choose, you will need a 1/2" nipple to connect it to the coupling you have welded into your keg. The "full thread nipples" are referred to as "close nipples". Either one you mentioned will do the job.
One thing I use when connecting any threaded fittings is to wrap the threads in 3 or 4 layers of teflon tape and make sure not to overtighten. Stainless steel gallls easily and screwing it right into brass is a no-no.
