This is the tool you need to straighen out my smaller aluminum lines.
The aluminum lines are shipped in a coil and if you want to run straight brake lines, for instance, you need a straightener.
Just squeez the alumium line with the nylon ends of the tweezers and pull the line throgh. I may even take a few pulss to get it as straight and smooth as you want.
Made of stainless steel with grooves for griping and nylon tips at the ends.
