Product Details
The single-size test-ball plugs are constructed from natural rubber, providing excellent expansion and memory, allowing them to effectively seal both round and out-of-round pipes. The plugs are equipped with a zinc-plated steel chain and a ring handle that serves as an anchor to prevent the plug from sliding down a line. They are designed to fit easily through test tees, sanitary tees, floor drains, and other tight situations, offering a broader expansion range compared to mechanical plugs.
