Presetting Tool
This presetting tool adjusts tubing ferrules prior to final assembly into a fitting. To use it, the installer first secures the tool in a vise, then removes the protective nut and assembles the fitting nut and ferrules loosely onto the tool. Then the tubing is inserted through the nut and ferrules until it settles in the bottom of the preset tool. After this, the tubing with the nut and ferrules can be removed from the body of the preset tool. Suitable for use in tight spaces and/or hard-to-reach areas, the tool is made from carbon steel and is available in sizes 0.625 in. and larger.
