Solid Rubber Stopper #6.5


A solid and tapered rubber stopper.  The #6.5 rubber stopper fits most carboys.

Usage tip:

When placing a rubber stopper onto a carboy, the goal is to produce an airtight seal.  Gently pressing the stopper into the carboy mouth will produce a seal.  Do not force the rubber bung into the carboy's mouth and risk pushing it through.
