Very good advice from Steve on this subject. I have removed some by pass fittings with a solid rod inserted inside, heat, and vise grips. If it does not move on the first attempt you might consider stopping, cause you will screw it up.
Like Steves example I have cut them out. On a by pass fitting cut it off flush and leave some material to tap on .
I like to make 3 cuts, once the first piece comes loose the rest is easy.
And don't be in a big hurry [img]<<GRAEMLIN_URL>>/naughty.gif[/img]
