The Cal-Van Tools Hydraulic in-Line Flaring Tool, No. 166, was developed because technicians needed to be able to apply more forming pressure with less effort. The tool combines features of an in-line flaring tool and a hydraulic flaring tool to provide a lightweight, low-profile tool. Designed to be easy to use compared to hydraulic-type and traditional offerings, this tool offers time savings and fits into tight-access areas. It also does single, double and bubble flares with the option to expand into quick-connect fittings, and it includes a constant tension tube cutter.
