Compression fitting lraks.
I am installing compression stop valves to copper pipe. They seem to require
a high level of torque to prevent leakage. Is this normal? I cleaned the copper with emery and then removed the debris. Would it help if I used some PTFE tape on the copper? If not, are there any other techniques I should use. Peter. |

No tape for this, if the tubing is not round they are a bear to get
right. And if your emery is leaving big gouges that might be your problem. PVR wrote: I am installing compression stop valves to copper pipe.

However, I have found that they seal better and are much much easier to tighten if you apply a little Teflon paste pipe dope to the compression ring. Don't clean the pipe; as noted, that will leave scratches. Jim |

Compression fitting lraks.
When I first bought my house, I used compression fittings because I was
afraid to sweat copper. Then I got so frustrated at compression fittings that leaked and all the trouble I had to go through to make them work that I knew it was time for a change. I bought a bunch of copper and fittings, all the stuff needed to sweat copper and spent a little time at the workbench learning to sweat. Once I realized how easy it was, I never used another compression fitting. I also tackled jobs I had avoided (like running hot water out to the garage) since swaeting is so much easier and cheaper. Do yourself a favor, buy a bunch of fittings and pipe and teach youeself to sweat in a no-pressure environment - at the bench. Good Luck!

I'm going to shorten the pipes by removing the emoried ends of about 5/8"
then reinstall the stop valves. Many thanks for your help. Peter wrote in message oups.com... No tape for this, if the tubing is not round they are a bear to get right.

BTW I have found that it is easy to over tighten the fittings. I would rather they be not tight enough than too tight. If not tight enough, I can snug them up, but if too tight, then It means replacing parts. -- Joseph Meehan Dia 's Muire duit |

Skip the emery, and don't use teflon or other tape.
The hint is to soak the fitting with penetrating oil before tightening. That makes the nut twist a lot better, and the ferrule slips into shape easier. -- Christopher A.

You can buy just the ferrules at the home cheepo. WD-40 works OK
for the penetrating oil. That should help with the lraks. -- Christopher A. Young You can't shout down a troll. You have to starve them. .. "PVR" wrote in message ...
