This tool is designed primarily for the fabrication and maintenance of Fire Tube Boilers with Tubes of 2”-3” OD. This self feeding, straight roll tool, is capable of simultaneously expanding and forming a uniform bead tight upon the tube sheet. For the best results we recommend a tube projection of 3/16” (5 mm).
