#15 Drilled Rubber Stopper (DRS)


The largest of our stoppers, this stopper measures 3 1/4" X 4" and is suited well as a stopper for wide mouth containers, such as mason jars. It also has a 3/8" hole drilled in the center, the perfect size for an airlock.

Our #15 rubber stopper is also available as a #15 solid rubber stopper (srs).
