Harris Solder Kit SB861 & SCPF4 - Stay-Brite #8 Silver Bearing Solder with Flux

This stuff is awesome. It holds well for HVAC work. Easier than brazing for sure.

Great flux and solder. I used it to install a new central split and had no leaks during a 500psi pressure test & 300 micron vacuum for 1 hour.One thing I had to do was cut off one of the swaged ends and expand it myself. The bell was just a tad loose and the StaBrite didn't want to fill it. I made a new bell that was a tight fit and the joint looked much better. It was probably ok, but I didn't want to risk having to do it again when it was inconvenient.This is good stuff and I highly recommend it. Adhere to good practices (scuff, tight fit, and don't overheat) and it works great for HVAC work. Easier than brazing and I trust having the larger bonding surface of solder more than the narrow bonding surface of brazing.

Nice product

I just installed a new central air conditioner I had to cut the lines and install new ends on them and I'm not experienced at brazing nor do I have the equipment I read that you can use this particular solder as it works for the regular torch and they're correct it works fantastic finished installing the air conditioner, vacuumed it down it's working fantastic

I love this Harris solder for HVAC applications. You can solder fittings at lower temperature without needing to run a nitrogen purge during brazing (brazing requires a nitrogen blanket to avoid heavy oxidation residue inside your piping). The only argument I have heard against this solder is that the flux leaves acid residue inside the piping. This can be avoided using a proper soldering technique ... sand/brush copper clean, fit together, heat, apply flux AFTER heating (this causes it to be wicked into the joint as necessary), then apply solder.

Great for plumbing work, but I would NOT recommend for HVAC work - although some use it. IMHO, It is too "wet" when heated and can wash into joints easily leaving loose beads of solder inside the refrigerant lines. Requires a careful attention to details.

Perfect! No issues. Exactly what i needed.

I tried this out on some scrap copper tubing, I was amazed how well it works, used a small torch bottle, you don’t need to get the copper as hot as using silver solder, highly recommend
