## Questions & Answers

**Q: Can I use it to fix  a tiny leak at copper pipe connection ? Thanks**
A: No. This is for attaching two copper pipes together, and it will need to cure for a little while before it gets wet. It won't help with an existing leak. I would try plumbers' putty, and if that doesn't help with the leak, you may need to pull the pipes apart. It'll cost a little money, but a plumber will be a big help.

**Q: Has anyone tried using this on flared hvac fittings that are having a problem getting a good seal?**
A: No, not tried. But can only imagine it would work well. However, flared hvac fittings shouldn’t really need this as they use threats, ferrules, and viton seals, correct? Anyway, I would just do an experiment: spend 10 on a bottle, assemble a capped tube using said flared fittings, and pressurize (standard pancake-style or alike 1XX psi compressor for pneumatic tools etc). Report back if pressure holds (compared to the control - compressor alone is good) ;)

**Q: Can it be used for jewlery making**
A: Probably not. I don’t think it would hold up to constant movement. I think it was a solderless method of bonding copper tubing and elbows together without using a torch and solder.

**Q: I have a turntable that only works on one channel, thinking there's a bad connection internally.  Would this product work for this?**
A: I had the same problem but after readjusting the two screws that attach the cartridge to the headshell the problem is fixed so I figured out the problem was the needle was not fit in the vinyl correctly, if it leans on one side then it only works on the channel it leans on, hopes it helps

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works as Wriitten its actually amazing and didnt expect the results too be so good
*by M***A on August 3, 2025*

Telling you what as in for not leaking and Fast clean hold.. This stuff is amazing .. bending the pipe back and forth under pressure yeah it will break but any mechanic and plumber knows compare it too locktight if you twist it enough or bend it it will break loose but a copper pipe in the wall or for a fix its as good as solder its amazing actually i never believed it would work... for the price and the big bottle you can do allot allot of pipe repairs for allot less money for solder and Map gas so a better value for the money for sure

### ⭐⭐⭐⭐⭐ Great product
*by A***M on July 20, 2025*

My copper pipes split apart at the weld during the winter and this product was a lifesaver. It actually worked . I tried different products including plumbers putty . This saved me from having to call a plumber in the middle of winter on the weekend and It’s still holding.

### ⭐⭐⭐⭐⭐ This, this is revolutionary.
*by A***R on December 10, 2024*

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.
