Get flaring and swaging tools from Grainger to help you expertly connect gas pipes and copper tubing. Use single-flare tools for most non-high pressure applications and double-flare tools in high-pressure applications, such as AC and refrigeration. A swaging tool can help you gradually widen the end of copper or other thin-walled tubing so one tube can fit inside the other and join them together.
