The Multi-size test-ball plugs are designed for underground applications and feature a unique design that allows one plug to fit multiple pipe diameters. Made from natural rubber, these plugs offer excellent expansion and memory, ensuring a tight seal for both round and out-of-round pipes. The removable inflation valve can be replaced if damaged or can be substituted with a quick disconnect fitting. These plugs are ideal for blocking flow or serving as a back plug during sewer air testing. They are an essential tool for plumbing professionals requiring versatile and reliable sealing solutions.
