Stubbing PEX out of wall using copper stubout!


Hey guys,

I am using a 1/2" copper stub ell to convert from pex to copper at the wall so I have something rigid to put a stop valve on. This is the exact stub ell I am using:

http://www.pexsupply.com/HydroPEX-H1...-Ell-3768000-p

Now one thing I noticed about this stubout is that it is very thick walled copper. So I tried a 1/2" compression stop valve on the end of it and it "fits" but is looser than a regular 1/2" piece of thin walled copper pipe (I could TRY to sweat it on but I'm worried the gap would be too big and solder might now flow into the joint). So I tried a 1/2" compression, wouldn't fit, pipe is too big. So then I tried a 5/8" compression and it fit but after tightening the hell out of it and using teflon tape, it is still seeping water. Now I can try to tighten it more or take it apart, re-teflon tape it and get a new ferrule and try again. But It feels like I'm missing something, why doesn't any valve fit right on this stub ell?

The stub out will work with no troubles. A 5/8 compression stop will seal to it without question. I use these all of the time. A trick of the trade......Throw away the teflon tape. Take the compression nut loose and add pipe dope to the compression threads, and a little on the ferrel. Tighten the joint, It will be easier to seal. If the ferrel is compressed to the point of compressing the copper, you will need to cut it off and try a new ferrel and dope. You should not go more than hand tight, then 1/2 to 3/4 of a turn with a wrench.

Hmm. Guess I'll take it apart and add some more tape and give it all I've got!
