3 in 1 manual tubing and pipe bender - Capacity and bend radii: Handles tubes with outer diameters of 1/4", 3/8", and 1/2" and bend radii of 0.82", 1.14", 1.43" (21 mm, 29 mm, 36.5 mm). - Material and durability: Made from aluminum alloy for superior durability and lighter weight than conventional steel bending tools. Provides corrosion resistance and strong performance. Suitable for bending copper, aluminum, soft iron, and thin stainless steel tubes. Note: when bending stainless steel pipes, thickness must not exceed 0.04" (1 mm). - Design and usability: Features an adjustable hook design that lets you adjust the hook position according to the pipe outer diameter before bending. This offers better stability and reduces effort during bending. - Angle range and operation: 0 to 180 degrees, providing a wide range of bend angles. User-friendly operation supports efficient bending. - Applications: - Bending copper water tubes for home plumbing and under-sink installations. - Forming copper or aluminum tubing for HVAC refrigerant lines and related work. - Creating lightweight tubing for DIY projects involving soft iron or thin stainless steel tubes.
