So I recently moved a radiator and I had to re-pipe the existing valve and elbow with new 1-1/2 pipe. I used ptfe pipe dope the first time I installed the original radiator union elbow. After a day I discovered a slow leak. Took it all apart and this time used both pipe tape and pipe dope. Leaked imidiately this time and worse. Finally I used pipe tape and jb weld epoxy putty. I put the putty all over the female hub, and some over the male thread that had tape. After tightening I formed it around the seam.
.....still leaks very slowly. I actually had a similar problem on the valve side and the jb weld is holding fine there. The threads all seem pretty clean, but is it possible that I bent the bronze hub when I had it in the vice? Is the tape maybe messing up the jb weld? Should I try one more time with just jb weld? I'm not even sure if I can get this app art after the jb weld, I was going to try heating it up with a torch. I also looked but I can't even find replacement angle unions that large if I wanted to replace it.
