What's the consensus here - should the PEX fittings be reused if the line
has to be cut and reworked? I cut some old PEX lines that I installed about
a year ago and I noticed that there was some blackish residue on the
fitting - rust from the galvanized to PEX interface most likely. But I
notice the discoloration and the fact that the crimp ring to some extent
distorts the fitting and it makes me wonder if I should discard old
fittings.

My instructions are vague about re-using a fitting. It simply says
...if you make a bad crimp - cut it out and replace it....

No mention of distortion in the fitting.

Well by definition it is a compression fitting - some distortion is
required. Doesn't mean it's automatically bad of course.

I would not be scared to cut the crimp off the fitting with a Dremel
tool and use the fitting again. Using the GO-NO GO gauge, the crimp
can best determine the proper crimp.

I'm sure many fittings have been used a second time.

I think you mean using a dremel to cut off the ring and use the fitting
again. This also assumes that the fitting (nipple) has not been deformed.
Unless the fitting is deformed or corroded it is fine to reuse the fitting.

How much money are you talking about? How much is "peace of mind" worth to
you? I'd go with new

Well my piece of mind is worth more than 2 bucks for an elbow fitting. I
have a big bag of them, PEX is usually sold in contractor packs, so I use
new anyway. But I was wondering about this as I tossed the old ones back
into the toolbox.

Are we talking about brass or plastic fittings?

EV-

Since they are brass & there are crimp cutters available l would get
that they are reusable

However, like Ed said "piece of mind"

Since you're doing th soldering experiment you could also do a re-use
experiment.
