Force Logic technology is the newest innovation brought to you by Milwaukee. Press copper fittings eliminate the time consuming process of soldering and brazing. Milwaukee's new Force Logic technology implements multiple sensors to ensure every press is perfect and leak free. M18 Red Lithium batteries increase run time and are compatible with over 40 cordless Milwaukee tools. Redlinks intelligence maintains even pressure throughout the entire press cycle and has a light that indicates the connection has been completed successfully. The maintenance interval for this tool is 40,000 connections and there is even a service light on the tool indicating that it needs to be calibrated. The tool is designed to be used one-handed thanks to a in line design that weighs only 8 lbs.
