A/C Line Swaging Tool

 A/c tube swaging tool.  The tool is made of solid coated steel to protect it from rusting while standing up to a hammer.  The tool is designed for aluminum or steel lines from 1/4" to 5/8" OD. 

We use this tool in our facility anytime we need to weld two fittings together.  The tool allows us to put a standard fitting (after cutting off the sleeve) into an aluminum tube for welding purposes.
