But, to actually determine the size of a pipe, the outside diameter of each pipe or fitting must be measured and compared to the table for size identification. NPTF threads have the same basic shape but with crest and root heights adjusted for an interference fit, eliminating the spiral leakage path. The threads are designed to seal mechanically by slightly, but sufficiently, crushing the threads when tightened with a wrench. Pipe fittings are "sized" by the "size" pipe they fit. For rigidity; sealable only with sealant; sometimes male straight enclosed by female tapered for low-pressure sealing.

After tightening with a wrench the threads may have slight spaces between the pipe and fitting which could cause a leak so a pipe sealant must be used to ensure any gaps are filled. These are the most common threads used for general purposes.
Tapered for sealing, often without any thread sealant; for connections in nearly every type of service.
The taper on the pipe only allows the pipe to screw inside the fitting until it is forced to stop because of the taper. NPTF threads have the same basic shape but with crest and root heights adjusted for an interference fit, eliminating the spiral leakage path. They include both tapered and straight thread series for various purposes including rigidity, pressure -tight sealing, or both.
But, to actually determine the size of a pipe, the outside diameter of each pipe or fitting must be measured and compared to the table for size identification.

Toggle navigation Help View Cart Contact. This allows for joining the pipe and fitting without sealants. Thus the inside diameter of a given size of Schedule pipe differs from the Nominal Pipe Size, while outside diameters for a given nominal Schedule size are the same between Schedules. The dimension in column 3 will be your nominal pipe thread size.
