This stopper is a bit larger than our standard plug. This stopper creates an airtight seal between the conical fermenter and airlock preventing any outside contaminants from ruining your beer. Don&';t let your airlock rest haphazardly atop the fermenter like some toy umbrella in an oversized cocktail glass. Replace your lost stopper today and let your airlock stand up straight and proud as it bubbles away protecting your precious brew.
