Solid Rubber Stopper #7


A solid and tapered rubber stopper.  The #7 rubber stopper fits most carboys.

Usage tip:

Although the #7 rubber stopper will fit the opening of most carboys, it will seat higher than the #6.5 rubber stopper.  Because it sits higher, there is little risk of pushing the stopper through and into the carboy, but because it sits higher, there is a greater risk of it getting accidentally knocked off.
