WebApr 4, 2016 · 3. Typically, most threads on pipes (in the USA at least) are male NPT and all the couplings or fittings are female NPT. You can connect two pipes with a coupling as long as the last pipe added is free to rotate about its axis. A union is used for easy removal of pumps and other serviceable equipment that would otherwise not be easily unthreaded. WebNPT male adapters have a taper thread that wedges into the female NPT adapter. They seal due to the "out of roundness principle," which means that the male stretches the female fitting until there is so much force that the connection can hold pressure.
