Why Don't You Sell Rubber Stoppers And Air Locks Together?

We are often asked why we don't sell a rubber stopper along together with our air locks, bundled together so to speak. I mean what good is an air lock without the rubber stopper to fit it to something? Well, the answer is really pretty simple.

Rubber stoppers come in all different diameters--from the size of a dime on up to the size of a orange. The size of rubber stopper you need depends on the what you are trying to attach the air-lock to. For this reason alone we will never be able to sell a rubber stopper and air lock together.

Glass wine carboys have a different sized opening than a gallon glass jugs for example. One takes a size #7 rubber stopper while the other one takes a #8. If you're using a plastic fermenter you may only need a size #2 rubber stopper. It just depends on the size of the opening.
