Nominal Pipe sizes do not match any of its actual physical dimensions. The OD of pipe / fitting must be measured & compared to the table for identification. threads per inch (TPI), but several sizes have the same TPI; because of this, both the TPI and OD of the thread are required for pos.
The NPSL thread series is designed to produce a pipe thread with the largest diameter possible to cut on a standard pipe. The internal and external thread dimensions are designed to have a “loose fit”, and a locknut with an O-ring is required to create a seal.
This guide provides details of these pipe threads, including dimensions, code designations and reference information. Parallel (‘straight’) thread whose diameter remains constant along the length of the thread.
The document provides specifications for end cap dimensions according to ASME B16.9. It lists the nominal pipe size (NPS), outside diameter, length, wall thickness, and other length for end caps from 1/2 to 48 inches.
