Cherne® Multi-Size Plumbing Test-Ball® Plugs have the same great features as our original test ball plugs, with the added benefit that one size fits multiple pipe diameters, doing the job of 2+ single-size plugs.

• Use to block flow (water DWV test) or as a back plug for sewer air testing
• Seals both round and out-of-round pipe
• Zinc-plated steel chain and ring handle acts as an anchor to prevent plug from sliding down a line
• Natural rubber provides great sealing properties as well as excellent expansion and memory
