Description: Pre-Swage tools can be used with Beswick compression fittings. The pre-swage tool is designed to swage the ferrule(s) onto the tube prior to installation of the tube/nut/ferrule assembly into the compression fitting body. Pre-swaging is especially helpful when the tube connection must be made in a tight space. In limited space applications it may be difficult to tighten the nut and ferrule assembly. Pre-swaging significantly reduces the effort needed to make these connections. Pre-swaging is also recommended to prevent accidental over-tightening of miniature threads and to increase efficiency during production.
