The MILWAUKEE® M18™ FORCE LOGIC™ Press Tool Kit w/ ONE-KEY™ with 1/4 in-7/8 Streamline™ ACR Jaws changes the game in refrigerant line installations, offering a flame-free, efficient alternative to traditional brazing. The ACR press jaws, compatible with Mueller Streamline™ ACR Press fittings, unlock productivity for HVAC system installers, eliminating nitrogen purges, combustible gases, and expensive silver solder necessary for brazing. As the industry's first press tool with remote tracking, management, and lockout, ONE-KEY™ allows for logging and uploading data from every press via the desktop or mobile app, making it the smallest, most intelligent press tool on the market. The state-of-the-art press tool features an in-line design and brushless motor, enabling more run-time per charge and faster cycle times while significantly smaller and nearly 20% lighter than the leading competitor. The in-line design with a forward hand position unlocks the ability to press with one hand and will fit nearly anywhere professionals can fit their arms. Milwaukee REDLINK™ electronics provide the highest level of press accuracy and reliability available in the industry. Auto-cycle ensures a full press every time, and the pre-press battery check prevents the tool from starting a press it can't complete. With 1/2 in to 4 in capacity (depending on material) and compatibility with over 20 unique fitting systems, the press tool is an optimal solution for HVAC and mechanical contractors.
