Working on HVAC, refrigeration, or custom plumbing projects? This tool kit is for creating flared and swaged connections on soft copper tubing. It includes a bit that attaches to a standard power drill to evenly expand (swage) or flare the ends of copper pipes, allowing for secure, leak-free fittings. It's an unbranded, new tool that comes in its packaging. Essential for professionals and serious DIYers installing air conditioners, refrigerators, or ice makers. Using the right tool ensures proper sealing, which is critical for systems holding refrigerant. Please note: specific dimensions (item length, width, diameter) are listed as N/A, so check the product details. No MPN or UPC. A specialized but invaluable tool for the right job.
