Teflon the threads on the union, 5 complete turns, then make sure the union has an o ring on it. Its the o ring that seals, hand tighten, then 1 1/4 turns more with a wrench.
Generally, that will probably be too tight. 3 wraps is usually adequate and more importantly, I would NEVER tighten a threaded joint much past about 1/2 turn more than hand tight. 1 and 1/4 complete revolutions should not be necessary,,,,,try the 1/2 turn before you go further.

the threaded joint that i'm trying to tighten into each of the 3 outlets in the multiport valve, the threaded joint has its own o ring on each of the three threaded joints?

I've put an o ring (was supplied in pack) on each of the threaded joints, the oring sits on the side of the thread that's not visible once 'screwed in.'
