After measuring, if you are still unsure, look at the listing from where you purchased your tumbler. They should be providing that information!

Inside Diameter: about 0.0.824 inches inches

Outside Diameter: about 1.05 inches




1/2 INCH PVC

Inside Diameter: about 0.622 inches

This is not a standard US size. This is usually the pipe that comes with your amazon cup turners. Check the listing from amazon to be sure.
