NPT threads (or National Standard Pipe Thread) are the technical standard for screw threads in the United States, most frequently used in threaded pipes and pipe fittings. NPT tap threads can be either tapered or straight, depending on the job at hand. The taper on NPT pipe taps means a seal is tightly formed when correctly torqued. This is due to the flanks of the threads compressing securely against each other (unlike straight thread fittings where the threads hold together without providing that tight seal).
