Schedule 40 Steel Pipe Nipple, 1/2-14 Male NPT, 1.50 Inch Long

For joining two female threaded connections, this is a 1/2-14 male NPT steel pipe nipple with male threads on both ends and a 1.50 inch overall length.

Standard 1/2-14 NPT threading is consistent across pipe fittings, so yes, this nipple will mate up with any standard half-inch NPT fitting. The 14 in that thread designation refers to threads per inch, and that's the same spec you'll find on valves, couplings, tees, and elbows made to NPT standards. No thread sealant comes pre-applied, so you'll want to add your own tape or compound based on what your system calls for.
