Cherne® 276128 Test-Ball® Multi-Size Pneumatic Plumbing Plug, 1-1/4 to 2 in Nominal, 40 ft Head, 1.25 to 2.1 in Range, Rubber

Cherne® plumbing Test-Ball® plugs were first introduced in 1953 as a more versatile product than traditional mechanical plugs. Designed to test drain, vent and waste systems Cherne Test-Ball® plugs could be used in any type of pipe, could be inserted through a test tee, and sealed out of round pipe as well. Cherne introduced the multi-size yellow-top Test-Ball® plugs in 2002. These test ball plugs have the same great features found in the original test ball plugs, but can be used in more than one pipe size.
