Description

4" Rubber "Econo" Test Cap. Height: 1 1/4". Item #1837508. A test plug seals a pipe opening so a drain or vent system can be pressure-tested, or a line isolated while it is being worked on. Tighten or inflate it until it grips the pipe wall firmly, and release the pressure behind it slowly before taking it out.
