4 Inch to 2 Inch Tri Clover Concentric Reducer for Kegmenter - Still AttachmentThis multi purpose 4inch to 2inch concentric reducer can be used for many different applications but most of our customers will most likely use this for attaching a distillation aparatus to one of our Kegmenters. This 4inch to 2inch Concentric Reducer is ideally suited to reduce the top of your Kegmenter to a 2 inch opening. This will allow both the AlcoEngine Reflux and AlcoEngine Pot still to be able to be fitted to the top of the Kegmenter.
