This provides uniform wall thickness without galling. It will put a 37 degree flare in 3/16”, 1/4”, 5/16”, 3/8”, ½”, 5/8” and 3/4” tubing. We recommend this tool when flaring 3/16” stainless steel brake line.

  • Feed screw handle requires less motion and effort than standard handle
  • Flares steel, stainless steel, hard copper and brass thru wall thickness of .035"
