1-1/2" slip fits over flexible or rigid pipe with an inside diameter of 1-1/2" or a 1-1/2" spigot. Because of the width of the tubing, the actual diameter is slightly greater.
The inside diameter of a 1-1/2" spigot is the same as the inside diameter of a 1-1/2" pipe. Fits into 1-1/2 inch slip fitting.
