Mechanical joining tools join tubing to flanges and fittings, creating secure, leak-proof joints that withstand up to 20,000 pounds of hydrostatic pressure. Superior to welded, brazed or crimped joints, mechanically joined parts will not leak, pull apart or loosen due to pressure, vibration or temperature changes. This proven method allows joints to be rolled to a torque or diameter specification. Rolling to a torque ensures consistent results, regardless of tolerance and variations of the tube OD, wall thickness and component ID. Rolling to a consistent diameter guarantees a consistent ID of the tube, which makes it possible to iron out and round up the ID of the tube. Virtually any annealed or ductile product can be mechanically joined, including mild steel, stainless steel, aluminum, titanium, Inconel and more. The tool is suited for applications common in the automotive, fluid power and aerospace industries.
