Overview
Standard length 304 stainless steel Tri Clamp Weld Ferrules give a good amount of tube to weld onto, with an overall length of 1-1/8" end-to-end.
For sizes under 1.5", this refers to the tube size, not the Tri Clamp size. All ferrules 1.5" and under have a standard 1.5" Tri Clamp ferrule. All sizes larger than 1.5" have a Tri Clamp that corresponds to the tube size. So, 2" tube with a 2" TC ferrule, 3" tube with a 3" TC ferrule, etc.
