The world's largest test ball, it blocks flow in the biggest pipes in sanitary and storm sewer systems, up to 120 in. The plug is the latest addition to Cherne's comprehensive, market-leading catalog of pipe plug, blocking and testing products. Cherne's 72-120 in. Test-Ball Plug was carefully developed with an optimized design that offers improved performance and safety. Accommodating a back pressure of up to 6 psi, the plug weighs 850 pounds and is 152 inches long. It is made from tough, tear-resistant natural rubber and features ¾ inch eyebolts that provide superior holding strength. A field-replaceable pressure relief valve prevents over-inflation, and an aluminum end plate minimizes rust and corrosion.
