Comprehensive set of seven interchangeable aluminum heads for bending pipes in sizes from 1/4" to 7/8", suitable for pipes with wall thicknesses from 6 to 22 mm and outer diameters of 1/4-7/8 inches with wall thicknesses of 0.6-2 mm, made from lightweight and durable pure aluminum construction. Capable of bending pipes up to 90 degrees in both directions, ideal for soft copper, aluminum, PVC, and thin-walled stainless steel pipes, suitable for various working conditions. Hydraulic drive mechanism reduces force required compared to traditional manual benders, allowing easy one-handed operation to minimize hand fatigue and enable longer work sessions. Simple three-step operation: tighten the oil return switch clockwise, press the movable handle, and release the oil return switch counterclockwise for quick bending, with no complex adjustments or specialized skills needed, making it beginner-friendly. Constructed from carbon-aluminum alloy for precision and durability, with easily replaceable parts and includes a portable toolbox for safe storage.
