This pipe fitting has NPT (National Pipe Taper) thread on both male and female ends. NPT is the United States standard used for pipe fittings. This fitting can be used to connect a female threaded pipe at one end and a male threaded pipe at the other end.

One common use of this pipe fitting is to extend the pipe through the wall to connect shower fixtures or tub spouts. Measure the required extension and use one or two pieces as needed. Use Teflon tape for a water tight sealing.
