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.
Features:
- Natural Rubber: Great sealing properties as well as excellent expansion and memory
- Schrader Valve Inflator: Includes cap with valve core tightener
- Ring and Chain Assembly: Prevents plug from dropping into DWV system during test
