Customers say
Customers find the bonding adhesive easy to apply and recommend it for copper projects or small pipe fixes. They mention it works well and is easier than using heat equipment and welding. Many are satisfied with the copper piping, speed, and bonding ability. However, some customers disagree on leakage, bond strength, and value for money.

Great stuff! Very happy with its sealing abilities
I had a plumber tell me that my water heater needed to be replaced because of the leaking from the pipes on top. He said they were welded, and to fix would require a complete replacement of the pipes and a professional welder would have to do the work⦠blah blah blah⦠this stuff fixes the leaks. I used it generously and reapplied after letting the initial application dry⦠so far so good. Itâs been a month and no leaks. Iâm sure it wonât last forever.

Life saver
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.

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. Iâll 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. Youâll need to re-sand the pipes and start again.I hope this review helps!

This, this is revolutionary.
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.

Doesnât work
Used for a hose bib, two days later after about a minute of use the holds failed completely, waste of money!

This saved us!
We paid a plumber to install a new shower in our very old house. He left before checking everything and afterwards we realized one on his joints didn’t fully seal so a little water dripped out when we turn the shower on. We couldn’t get ahold of him to come back to fix it so I found this on YouTube and decided to give it a shot. I was simply too intimated to use a blow torch and unwilling to pay another plumber. It worked and was super easy to apply. I kept the shower access panel open during every shower to ensure the seal held and several dozen showers later it’s held up just fine. So glad this product exists and was so simple to apply.

It works, just except a learning curve and leaks until then.
Had very good luck using this for capping off a copper pipe, also worked on couplers just remember if you have even the slightest bit of water touch this stuff game over as it âwillâ leak although with a little heat the fittings come right off. The best thing about this for me was using it to glue a chrome plated copper drain line to the inside of the main copper line, as those who know the chrome plated copper is slightly smaller in diameter than the inside diameter of the standard copper pipe, once all of the connections are made I simply drip copper lock in the small gap between the two pipes, tried it first with 2 scrap pieces to make sure it works as I do not want sewer vent gasses coming into the house, honey whatâs that smell!

Very good product

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 tapeand 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 taband 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.
