The goof plugs are basic, common accessories used in the layout and installation of a micro irrigation system. The plug has two sizes and comes as a strip of ten.
To plug holes from drippers or any other 1/4" hole insert the small end of the goof plug in the empty hole. If the hole was a larger size or if the small size does not seal the hole try using the larger side of the plug. If the plug does not seal the hole then cutting out the section and using a coupling for the size tubing is the alternative.
