Product Details
The Multi-size test-ball plugs (underground) are designed to accommodate multiple pipe diameters with a single plug. Made from natural rubber, these plugs provide excellent expansion and memory, enabling them to effectively seal both round and out-of-round pipes. The removable inflation valve enhances usability as it can be replaced if damaged, or swapped out for a quick disconnect fitting. These plugs are specifically intended for blocking flow or serving as a back plug during sewer air testing.
