These stainless steel ferrules are 1-1/8" long (1" jacket, 1/8" flange). Perfect for soldering, brazing, or welding to a 2", 3", or 4" column. These ferrules are made so that their respective diameter pipe will slide over top of them.
The 2" ferrules can also be used as an adapter for beer keg flanges. The outside diameter of this ferrule will match the sanke fitting of a beer keg. A flat silicone washer is recommended as a gasket.
