The equipment in use
How this item fits your brewing setup
These stoppers are the replacement-interface option when you already have an airlock but need a bung that suits the vessel opening. Each has a tapered body and a drilled passage for the airlock stem. Choose the stopper for those two connections rather than assuming that a stated carboy gallon size defines the neck.
The selected listing specifies number 10 stoppers with a 52 mm top diameter,43 mm bottom diameter and 0.39-inch airlock hole. The height is listed as 1.26 in. Those measurements describe the stopper body and passage; they do not establish that every part sold as a standard airlock will fit.
The package contains six drilled rubber stoppers. Airlocks and vessels shown in usage scenes are not established as supplied. This is therefore a useful comparison when replenishing closures for compatible equipment, while a complete airlock-and-bung set addresses the different need to obtain both parts together.
Compare your vessel opening with the taper and your airlock stem with the drilled passage before ordering. The supplier’s broad 3-, 5-, 6- and 6.5-gallon wording is not a substitute for those measurements. If a particular cleaning cycle is important to your setup, confirm that the actual stopper is suitable before choosing it.

Questions about this product
What else should you know?
Are the airlocks in the usage images supplied?
The supported package is six drilled rubber stoppers. Choose compatible airlocks separately if you need them.
Can I replace a number 6.5 stopper just because both are drilled?
Match the actual opening and taper. The number 10 dimensions here are not a claim of interchangeability with a number 6.5 stopper.
Does this use the same airlock passage as the Speidel FE780 stopper?
The published passage here is 0.39 in; the FE780 replacement lists 11/16 in. Those are different specifications, so do not assume the same stem connection just because both parts are drilled rubber stoppers.
