NPS stands for Nominal Pipe Size. It's a dimensionless number used in North America to indicate the size of pipes, valves, and other related components in a piping system. It's not a direct measurement of the pipe's actual dimensions, but rather a convenient way to refer to a specific pipe size.
Please refer to OD, ID and Wall for actual size of pipe.
