While AN fittings depend on the outside diameter of a tube for sizing, NPT fittings depend on the interior diameter (I.D.) of the fitting itself. The following chart shows the each size's thread-per-inch count, the I.D. of the fitting, and the AN fitting size with the closest-matching I.D.(inside dimension).
AN / NPT / Metric / INCH (SAE) Conversion ChartsWhile AN fittings depend on the outside diameter of a tube for sizing, NPT fittings depend on the interior diameter (I.D.) of the fitting itself. The following chart shows the each size's thread-per-inch count, the I.D. of the fitting, and the AN fitting size with the closest-matching I.D.(inside dimension).
NPT - National Pipe Thread Tapered - is a U.S. standard for tapered threads used to join pipes and fittings is defined by ANSI B1.20.1 Pipe Threads, General Purpose, Inch; NPTF - National Pipe Thread Tapered Fine - also called Dryseal American National Standard Taper Pipe Thread -is a U.S. standard for tapered threads used to join pipes and fittings is defined by ANSI B1.20.3
Basic Dimension of National Standard (NPT) Pipe Threads NPT = symbol for the thread series and form (i.e., National (American) Standard Pipe, Taper) L 1 = Length of normal hand-tight engagement. This is also the L1 gauge length. (Longer thread engagement may be used in special applications, such as flanges for high pressure use. In such cases the pitch diameter, E, remains as specified and the
How to Measure National Pipe Threads (NPT) Correctly Jul 02, 2020 · Check out the chart below for guidance on measuring National Pipe Threads (NPT). For additional guidance on other pipe threads, please view this reference guide from Eaton Weatherhead. National Pipe Tapered (NPT) Thread Chart. Measure thread diameter and subtract 14 inch to find the nominal pipe size.
For example, a 3/4" NPT pipe thread has an outside diameter of 1.050 inches. Each thread size has a defined number of threads per inch (TPI). The 3/4" NPT pipe thread has 14 threads per inch. Both the TPI (threads per inch) and OD (outside diameter) of the thread are required for positive identification of thread size because several sizes

NPT & NPS Threads NPT is NATIONAL PIPE TAPER (AMERICAN) Thread form per ANSI/ASME B1.20.1 NPS is NATIONAL PIPE STRAIGHT (PARALLEL) Thread form per ANSI/ASME B1.20.1 NPTF is NATIONAL PIPE TAPER FOR FUEL Thread form per SAE J476 NPSM is NATIONAL PIPE STRAIGHT MECHANICAL
Male NPT threads may be designated as "MPT." The pipe size is often written such as this 1/8"-27, with a hyphen between size & thread per inch, and pronounced as "one eighth twenty-seven" Three less common threads exist, the Garden Hose Thread (GHT), Fire Hose Coupling (NST) and British Standard Taper Pipe Thread (BSPT). The NPT and NPTF

Technical InformationNPT threads in that NPT threads are designed for mechanical or low-pressure air or fluid applications. Visually, the two look identical. However, the thread forms are different. Mating a NPT threads with NPTF threads will most likely produce a connection what will leak. All of our hydraulic fittings and adapters are NPTF threads.
Common pipe thread mainly include the following:NPT, PT, G and so on. a.NPT is the abbreviation of National (American) Pipe Thread, belongs to the American standard 60-degree vertebral thread, for North America, GB refer to GB / T12716-1991.
Understanding NPT, NPTF & NPS Thread ConnectionsThe requirements for NPT (National Pipe Thread) are spelled out in ANSI B1.20.1 The requirements for NPTF (National Pipe Thread Fuel) are spelled out in ANSI B1.20.3. Both NPT and NPTF have the same threads-per-inch, pitch diameters, and taper-per-inch. The differences come in the major and minor diameters, the root and crest of the threads.NPT Thread Chart with NPT & NPS Pipe Fittings Dimensions Nov 29, 2016 · NPT THREAD SIZE & PITCH:DASH SIZE:MALE THREAD MINOR OD:FEMALE THREAD ID inch TPI:mm:inch mm:inch:1/8 27-02 9,9 0.39:8,4 0.33 1/4 18-04:13,2 0.52 11,2:0.44:3/8 18 -06 16,6 0.65:14,7:0.58:1/2 14-08:20,6:0.81:17,8:0.70:3/4 14-12:26,0:1.02:23,4:0.92:1 11.1/2-16:32,5:1.28:29,5:1.16:1.1/4 11.1/2-20:41,2:1.62:38,1:1.50:1.1/2 11.1/2-24:
