Specifications for PVC pipe and fittings for water supply. The second system for sizing PVC pipe is based on the Standard Dimension Ratio , a series of ratios of outer diameter to wall thickness. The minimum wall thicknes, times the SDR is the OD of the pipe. Associated with each SDR size is a class number, which is actually the working pressure for the pipe in pounds per square inch. All sizes with, Nominal Pipe Size Nominal Pipe Size (abbreviated NPS) is a North American standard for identifying pipe sizes. Technically, the NPS is non-dimensional and only roughly refers to the diameter of the pipe. However, from NPS 14 and above, the NPS value.

PVC Pipe sizes are different than the size the pipe is called. For example, a 1 inch PVC Pipe is actually 1.315 inches in outside diameter, and 1.029 inches in inside diameter. Fittings follow this same pattern, a 1" fitting has a 1.315 inch opening to accept a 1 inch pipe, which actually measures 1.315 inches in diameter.
