Works MUCH better than a 3/4 and 7/8 tube 3-flame nozzle. Works well for a 3/8 pipe if you're working really fast. I had to replace the first one as two of the flames were out of sync with the other three. The replacement product worked great, as did my 3-flame hook of the same type. You'll wonder how you ever lived without them, especially how easily and quickly they allow existing connections to be disassembled or rotated, which heats up the rest of the assembly less.
