Copper Lock 10 ml, No Heat Liquid Solder for Copper, Brass & Yellow Metals, Instant Leak Proof Seal up to 500 PSI, -60°F to +300°F, Bonding Solution for Plumbing & HVAC (10-801)

I had some pieces of 1/2" copper left from a project and wanted to build a plant stand. I needed it to be secure and strong so I could pick it up and move it around and not worry about it coming apart. This worked great! I tried to pull the pieces apart and it is solid. So easy to use! I also purchased a similar one from my local Ace Hardware but this one was about 4x as big and cheaper and this one worked at least as well if not better.

I replaced my gas water heater and needed to reattach the copper overflow pipe from the pressure release valve. I don’t have experience with copper solder so this was a great alternative. Very easy to use and appears to be a solid bond. I honestly don’t know if I would trust it if the copper pipe was under constant water pressure but for my application it is perfect. If the pressure relief valve pops and water flows into the overflow pipe I am having a bad day and it isn’t going to matter if the pipe leaks a little!

Wow! This worked great. A friend of mine said it wouldn’t work, but I had a rusted leaking receiver drier on my old R-22 system, I cut it out and replaced with a new one and used this to reconnect it and no leaks, system has been performing great for 6 months now. Even more impressive is that this is close to the condenser and gets a lot of vibration and it’s holding up great

worked great, just not thick enough.

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.

Didn’t work for me on the first try and I haven’t tried again.

Not a review of the product but rather the packaging. Why do companies do this crap. This bottle is half full. Not complaining that I didnt get what I ordered, but why not just put it in a smaller bottle. It looks silly and and is just a waste of plastic.

Holy smokes! Is it glue or soldering? No torch, no heat, it can say soldering on the package all it wants, but it really looks to be just glue. But WHO CARES; it worked like a charm! Tried this because I was working on a gas boiler... it did the trick, has been holding approx 20psi and no sign of leaks - I don't think I'll go back to the torch unless forced.

Pegamento fuerte y fácil de usar, resultó mejor de lo que esperaba.

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.

My 2008 Yukon had one read defog tab ripped off. I tried a product from a store specifically to 'glue' it on - no good - completely disappointed. I used this in with a piece of copper tape which I got on amazon. The copper tape is conductive on both sides - yes - including the sticky side. Clean the area on the window so there is no dirt. I used a 1.5" long piece of conductive copper tape and taped it over the area on the glass where the tab is supposed to go. Rub the tape firmly on the window. Then, I used this product to 'glue' the tab to the copper tape I put put on the window. Prepare the tab by sanding it so it is shiny copper. I poured a thin layer of the red liquid on the back of the tab and placed it in place on the copper tape. Apply good pressure for 2 whole minutes AND DON'T MOVE IT. It stuck. I let it be for 10 minutes and then gently and carefully placed the electrical connected on the tab. I turned on the rear defog switch and used a multi-meter to determine there was voltage on the window. There was..and it works. It's too bad that they don't sell a smaller bottle. I only used about 15 drops in total. Good luck to you.

Very good product
