The Single-size Test-ball Plugs are designed for underground use to effectively block sewer flow or serve as a back plug for sewer air testing. Constructed from natural rubber, these plugs provide excellent expansion and memory, ensuring a secure seal on both round and out-of-round pipes. The design includes a removable inflation valve that can be replaced if damaged or swapped with a quick disconnect fitting. Additionally, an eye-bolt is incorporated for use with a poly-lift line, enhancing usability and convenience.
