Rubber Stopper with Hole
We supply seven rubber stoppers with a hole. These stoppers are made with latex. Refer to the size specification chart to determine which size is for you. These rubber corks are popular for creating airlocks on jars and bottles to ferment vegetables, make wine, and brew beer. Purchase a 3-piece airlock or an s-shaped airlock to make your DIY fermenter. These high quality rubber stoppers keep out unwanted bacteria and particles and create delicious home ferments. Rubber corks are sold individually.
