I'm a little curious about something and am hoping somebody here knows the answer. Everything I've read indicates that up through 3/8 inch tubing is supposed to get a double flare, but all the tool places sell single flaring tools of this size. I know the double flare tools are available also, I'm just wondering why everybody sells a tool that performs an ill-advised operation. ![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
