1. Complete 7 Dies Set : This hydraulic pipe bender comes with 7 interchangeable aluminum bending dies ranging from 1/4" to 7/8". It fits outer diameters 1/4–7/8" and wall thickness 0.6–2 mm. Made of solid aluminum, it is lightweight yet sturdy. 2. Two-Way 90° Precise Bending : It enables accurate bidirectional 90° bending for copper, aluminum, PVC and thin stainless steel tubes. Even bending avoids tube cracking and distortion, fitting multiple pipe materials. 3. Labor-Saving Hydraulic Power : Hydraulic structure cuts operating force greatly. One-hand operation is achievable with less hand fatigue, ideal for long continuous work, much easier than conventional manual benders. 4. Simple 3-Step Operation : Just tighten the oil return valve clockwise, push the handle, then loosen the valve counterclockwise. No complicated settings or professional know-how needed, friendly for new operators. 5. Extensive Application Scenarios : Perfect for air conditioner repair, floor heating, ventilation engineering and pipeline maintenance. Compatible with copper, aluminum, thin stainless steel and PVC pipes for household and professional jobs.
