Cherne® Single-Size Test-Ball® Plugs are designed to test drain, vent and waste systems in every type of pipe. They also can be inserted through a test tee to seal out-of-round pipe. 

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.
