Comstar 10-800 Copper Lock, No Heat Solder, 2 oz. Plastic Container

Very good product

My husband and I have given each of our 3 children one of these because you just never know when it will come in handy. Our daughter did use it during a snow storm and worked like a gem.

Replacing an evaporator inside a residential refrigerator

This soldering liquid is the boss! My basement lock off started leaking and I had to change the whole thing to a more modern valve, the piping is copper, instead of buying soldering equipment I got this for a fraction of the cost, and it is superior in performance,saving time, money, and above them both, no risk of burning anything.

Pour tous ceux qui ne sont pas capable de souder ou d'installer des tuyaux de cuivre dans des espaces très restreint, ce produit est dispensable.

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!
