Product Details
The Multi-size Test-Ball Plugs (underground) are designed to accommodate multiple pipe diameters with one plug, featuring natural rubber construction that provides excellent expansion and memory. These plugs effectively seal both round and out-of-round pipes. Each unit includes a removable inflation valve, which 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 for sewer air testing.
