Product Details
The Multi-Size Test-Ball Plugs (underground) are designed for versatility, as one plug fits multiple pipe diameters. These plugs are constructed from natural rubber, providing excellent expansion and memory, which allows them to seal both round and out-of-round pipes effectively. The plugs feature a removable inflation valve that can be replaced if damaged or can be substituted with a quick disconnect fitting. They are suitable for blocking flow or serving as a back plug for sewer air testing.
