Leaking Bushings - Hot Water Boilers

LSF Member Posts: 3
Anyone having difficulty with larger (5" - 6") bushings leaking at threads on hot water heating boilers such as Peerless 211A or Weil McLain LGB series? We have tried all commercial products we are aware of. The bushing will hold for a day or two and then leak, sometimes an actual stream of water.

    i work with use pipe wicking on fittings 3" and up. I never used it myself though, but seems to work for them...

    Did you....

    I've noticed with larger bushings made "elsewhere", there is usually a line that looks like a seam running across the threads. Always thought it was where the dies stopped. Perhaps it is a seam.

    How about a nipple and reducer coupling?
