The outside diameter of a 2-inch PVC coupling is typically larger than 2 inches to accommodate the pipe it connects. For a standard Schedule 40 PVC coupling, the outside diameter is usually around 2.375 inches. It's important to note that the "2-inch" designation refers to the nominal size, which is the inside diameter of the pipe the coupling is designed to connect.
