• ### Basic Principles Of Tube Expanding

Roll the tube to what you estimate to be a good tube joint (by feel or an estimated torque setting) and check the ID of the tube with a tube gauge. Take caution not to over roll as it can cause damage. Subtract "F" from the rolled diameter to determine the actual amount of expansion (tube wall reduction) on the inside diameter of your tube. This can be converted to a % wall reduction .
