Pipe Fittings

What is a pipe fitting?

Pipe fittings are threaded components that connect piping to other piping in a variety of configurations.  While there are several types of pressure tight threads used around the world, the U.S. has standardized on fractional NPT (National Pipe Thread).  Thread sizes generally range from 1/8” NPT to 4” NPT, and are related to the nominal ID (Internal Diameter) of the pipe.  For that reason, if you measure across the outside diameter of a ½” NPT pipe it is actually about ¾” across.  Generally pipe fittings can be brass or bronze, black malleable or galvanized steel,  304 or 316 stainless steel.
