I know they aren't commonly used, but I have some. I know why they aren't commonly used, because it's harder to get the cutoffs to line up when properly tightened.

So let's say I have that problem because I do, how would a plumber normally deal with this from the beginning, and if you already have this problem, would it be a bad idea to re-heat the joint with a torch (map gas) just long enough to turn the adapter/cutoff assembly just enough to line it up (no more than a quarter turn)?

TIA!
 
It's a copper piece that has threads on it. You sweat it on copper pipe to give it threads so you can use threaded cutoffs instead of compression stops.
 
1/2 inch IPS to 1/2 inch CTS male adapter.
IPS iron pipe size CTS copper tube size.

Oh, a male adapter.

We just thread on a IP angle stop until it lines up straight.
Though my preference is always compression. We can remove those with a sleeve puller. We replace maybe 15 compression shutoffs a week with the puller. It's a lot neater job then soldering.

I know it's not a common preference but I like it. Unfortunately they aren't lining up, they have to be tightened past being vertical, but not so much as to come all the way back around, otherwise they leak.
 
Just be glad you aren't sweating on male adapters inside the cabinet. It's real easy to burn wood there if your're trying to get close to the wall.
 
Any suggestions though?

I guess you could tighten it until it's snug and not leaking, make a mark on the male adapter that indicates where the stop is at when it's straight up, then take the male adapter off and sweat it again using that mark.

Would it be wrong though to heat it up and simply turn the male adapter so that the stop lines up?

I know it can't be wet but I'd imagine you could dry it out somehow.
 
Or you could throw a couple wraps of Teflon Tape, and then pipe dope over that, and tighten until it's straight up.
It doesn't have to be arm chair tight. The trick is learning when to stop.
 
Don't tighten it that far, or get a bigger wrench and tighten it the rest of the way. Heating an assembled threaded connection will often cause a leak because of the difference in expansion/contraction of the two pieces.
 
Back to the first basic question: YES, it would be a bad idea to heat it up and turn it. That very likely would result in a leaky joint.
 
I'm only tightening it as far as I have to to get it to stop leaking. I've already done the two wraps of teflon and pipe dope.
 
LOL. I guess there are enough threads left to get it back around, I'd just be worried about breaking the sweat joint. Is that an irrational fear, or should I do something to keep that from happening while I tighten it?

BTW how old is that picture?
 
You should be backing the fitting with a wrench while you are tightening the shutoff. Two wrenches.

That picture was when I was fifty. I had climbed Mt Rainier a few weeks before and was in pretty good shape.
Though I'm still 210 even after last year. My arms look like I work out even at the age of 59. It's just from lifting boxes that weigh 100 pounds and two garage doors at once. In softball, I still hit the ball over the outfielders heads. I'm not that old yet. Last Summer I was batting .720 with triples and doubles, and doing chemo at the same time. My avatar picture is from last Summer at a Seahawks game. My son Taylor is going to school in Boston this year.
