25 rowsNational Standard Taper Pipe Threads Size NPT Chart - Includes both External and internal Pipe Thread Data. The taper rate for all NPT threads is 116 (34 inch per foot) measured by the change of diameter (of the pipe thread) over distance. The angle between the taper and the center axis of the pipe is 1° 47' 24" (1.7899°).(plate) What ' s The difference between NPs and tapered pipe?What ' s The difference between NPs and tapered pipe?NPS, National Pipe Straight, is the American standard for parallel or straight pipe threads. NPS threaded connections need gaskets or O-rings to seal them. Tapered pipe threads need a sealant for leak-free connections. It fills any voids between the two threads that could cause a spiral leak.Tapered Pipe Threads and Fittings Making the Connection
