This #7 Solid Rubber Stopper (SRS) has a top diameter of 1 7/16" and a bottom diameter of 1 3/16". This 7 solid rubber stopper does not have a hole drilled in it, making it perfect for use if fermentation is done or for storing clean and dried containers.

Also available as a #7 drilled rubber stopper (drs).
