NPT and NPS are the same. Screw away! If your female thread is plastic and your male thread is metal, you must be careful not to overtighten as overtightening can crack the plastic on the female thread. Good luck, and don't forget your teflon tape. 4 to 5 wraps is good unless you have heavy duty gas piping teflon, then use less.
