Only because I've never seen it mentioned...

I accidentally cracked the flange of a Milwaukee nipple awhile back, while tightening it against a permaseal (I tried one this once, and will never do so again - standard nylon washers are dirt cheap and work flawlessly). I drank myself into a stupor out of frustration ...and several weeks later, had the presence of mind to wonder if the rest of the flange could simply be chipped off. 5 minutes of experimentation with a chisel and hammer left me with a (very) roughly flat surface, and I used that regulator for several months afterward with a couple (I refilled the cylinder) nylon washers.

I've since upgraded my regulator - a couple of times - and am happy I did. But that flange is just an annoyance, which can be dealt with via simple tools combined with brute force.
