Very tight flare nut

So my method is chop off the pipe flush with the union, then use a single hex socket to unscrew the union from the flexi

If you don't already own a pipe flaring tool, I can recommend this as to my own choice LINK


You will in all likelihood want to get a pair of THESE too

Best of luck

All items ordered and on their way. Many thanks for the great advice. The rear rigid pipes were supposedly replaced about five years ago, but I guess that's plenty of time for more corrosion. 3/8" too small, 7/16" too big on the flare nut in question, so no better than the metric. When all the bits are in place I can get properly serious lol
