FOR REFERENCE ONLY! This information is a reference guide only. Specifying the correct schedule of pipe and fittings depends on many factors. It is the ultimate responsibility of the end user's piping engineer to specify the correct pipe schedule which will meet the maximum operating pressures and temperatures of the system for safe operation in the intended application.

Always verify the rating with the manufacturer of the pipe you are purchasing to confirm it is the same as the information provided below. And always make sure that the products meet the requirements of applicable plumbing and building codes and the authorities having jurisdiction (AHJ’s).
