Rated 1.0 out of 5 by 4 reviewers.
Rated 1.0 out of 5.0 by You will be sorry These fittings are junk. The half that threads onto 3/4 pipe will leak . I spent two hours before I pitched them in the garbage . Bought them at White Lake,mi store . I will let them know at the store. I can't find the half that I threw in the garbage. February 7, 2015
Rated 1.0 out of 5.0 by female thread leaks Had same issue with leaks around female thread as other reviews mentioned. I had two of these unions. One leaked, the other did not. December 7, 2014
Rated 1.0 out of 5.0 by Use with caution! Use plenty of pipe dope AND teflon tape if you don't want these to leak. Inner female threads are machined too deep. November 28, 2014
Rated 1.0 out of 5.0 by Threads not well machined - leaks Manufacturer needs to note we have purchased five and only one does not leak. We need two. We noticed the threads are not clean, tool chatter when machining. Have sanded a little as not to tear t-tape. Total poor quality. Big waste of time. January 6, 2014
