Rollers take the wrinkles out of tube bending


Most benchtop tube benders risk damaging tubing while making bends. Most benders also tend to create ovality along the tubing's bend radius. To reduce these problems, the new Bench Top Tube Benders from Swagelok Co., Solon, Ohio, use rollers instead of slide blocks, along with a sturdy bend shoe. Available in electric and manual versions, the benders deliver consistent bends from 1 to 180 in 1 increments, and work with tubing materials such as steel, carbon, stainless steel, copper, and aluminum. They handle tubing from 0.5 to 1 in. (12 to 25 mm). The benders are lightweight and ruggedly constructed, and can be mounted on a workbench or a portable tripod
