The Milwaukee M18 2674-20 Short Throw Press Tool is not for copper fittings; it's specifically designed for PEX tubing (Viega PureFlow PEX or similar F1807/F2159 rings). Using copper press jaws on this tool won't work because the jaw patterns are different; you need a separate Milwaukee Force Logic press tool for copper, along with compatible copper jaws, as the short-throw tool is for PEX only.
