The Multi-Size Test-Ball Plugs (Underground) are designed to fit multiple pipe diameters, making them highly versatile. Constructed from natural rubber, these plugs provide excellent expansion and memory, ensuring a tight seal for both round and out-of-round pipes. Each plug comes equipped with a removable inflation valve that can be replaced if damaged or upgraded with a quick disconnect fitting.
