Review on Allstar Performance ALL50110 Inverted Flare by Travis Karren

The swivel nuts worked well and were almost perfect. Each fits normally in the pipe. The carving was good too and they didn't feel soft or "rounded", they also held tight to the key which is good because they weren't round! The only thing I noticed was that they had an extra coating on the inner hole 2/3 of the way up from the thread start point, but that didn't affect functionality. The threads may be stripped and the hex does not affect the tolerances to fit the wrench. I don't know.
