Bets paint stripper to get emulsion off copper

Got to work on an old bit of 15mm copper that's been painted.
Does any paintstripper work on emulsion (I have never tried, oddly enough).
Can't scratch/sand it off as I need a surface that will take a
compression fitting. Burning off is dicey as it's right up close to
plastic (which precludes a solder joint).
Cheers,
Tim

In article <rsaocc-...@squidward.sv.dionic.net>,
I think you'll be lucky to find any paint stripper that works on anything
these days, outside of industrial stuff. The active ingredient of the old
- which worked just fine - seems to have fallen foul of H&S or whatever.
Had some Nitromors lying around - yonks old - and used it to start
stripping ordinary gloss paint. Which it did beautifully. Ran out and
bought some more. Which didn't touch it at all - despite the high price.
If you do find one which works, let me know. ;-)

Swarfega and a bit of time is one way that works fairly well for me. The

paint will soften after about an hour and come off in strips fairly
easily. It works on some gloss paints too.

It was common practice to file gloss paint of copper piping and use a
compression fitting.
Last time I did this was in 1999, somebody had smacked a Yorkshire elbow on
the copper pipe to a fire hose and it was pissing out.
We used a compression fitting as we were not geared up for soldering. I was
not in plumbing, I was in fire protection and we had to go to B&Q for the
fitting.
I'm sure that if you just sand the emulsion off the copper, a compression
fitting will be fine ------------ bit of PTFE tape just to make sure.

It works very well where there could be doubt about the surface of the
copper.
It worked very well when I had to use a compression fitting on the copper to
the fire hose, after using a file.
Many plumbers do it.

wet-or-dry. Although I do use very fine WOD, and make sure the
scratches, fine as they are, go around the pipe, and not along it.

the pipe, then I don't see why PTFE would help. I feel so many people think
it is th esolution to everything - but without a proper side by side
comparison of identical methods (with and without) then you don't know that
it helped. PTFE is for threades joints - a compression uses the threads to
compress the olive and are not part of the sealing process.

You could just buy the active ingredient of old Nitromors:

And, to tackle the hoary myth about PTFE on compression fittings, it is
absolutely fine to put three turns or so on the male threaded portion.
Not for sealing, but to reduce the friction (so that you get more axial
load for a given amount of torque).
Try to avoid letting filaments go into the cones or across the olive,
but *small* amounts even there will not matter: at the pressures
generated in a compression fitting the PTFE will just extrude.

amount of torque, you get more axial force (which is what makes the
olive seal). It doesn't make much difference on brass fittings, but it
makes more on steel and chrome plated ones.

Indeed - I think the compression article says much the same:
