Great Product for homeowner pluming jobs
I used this product to install a baseboard radiator with 3/4" copper pipe and followed the instructions. It worked perfectly! I used a copper pipe cutter and 80 grit sanding cloth for the pipes. The product is a bit runny, which was actually helpful for connecting to a pipe inside the wall. I used SharkBite caps to seal the ends and pressure test the system for leaks before installing drywall. I was thrilled to avoid soldering the pipes. I’ll update you on its performance after the heating season.P.S. If you need to disassemble the joints, have two grip lock pliers ready to turn the pipe and break the seal. You’ll need to re-sand the pipes and start again.I hope this review helps!

Soldering copper pipes
I used this to solder an outside faucet. One of the pipes connected to the faucet came apart at the solder due to the freezing weather. I did as the instructions said by sanding the pipe and connector. Next, I put the liquid solder inside the connector and on the pipe. I then gently tapped them together. I waited over an hour before turning the water and over a day before allow full pressure. To my amazement, they so far have held together. I did add a little more of the liquid solder than was recommended.

Probably, just not for my job
Based on opinion. I believe this product would work in most cases. Cases that the joint would never have any considerable force upon it. I used it on a shower elbow. It held only for a short time each time. But because I believe it would work much better than any other circumstance but did not work for my particular job. I gave it the three star

works very well on copper pipe
I had a tough repair (access). This product stepped up and made the job doable. Highly recommended.
