The NAVAC NTB7L helps HVAC technicians bend large diameter tubes at precise angles. Suitable for tubing sized 1/4 to 7/8 in., the NTB7L works by pressing a single controller switch to bend tubes to any angle. When a bend is completed, the baffle will push the tube out automatically while the tool resets, making removing the tube effortless. The lithium battery can make over 100 bends on each charge, and can be fully charged in 30 minutes. The reverse bending kit NTBRK is available separately.
