If you have an irrigation drip line system that feeds several plants and sometimes you dont use all of the drip lines you have available, you can temporarily block them off with an Irrigation Goof Plug.
These Irrigation Goof Plugs simply push into the end of your drip line to prevent any water escaping and they can easily be removed when you need to use that drip line again, without the need to cut any of your pipes.
Irrigation Goof Plugs can be used with 3mm and 4mm drip lines to cap their ends.
