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

I was moving my 5 ton air handler with A-coil from horizontal to vertical and had to make 6 solder connections which I haven't done in over 50 years and some people think only brazing is sufficient, but brazing wasn't even used back then, anyway all went well and everything is working fine. My only complaint is 4 out of my last 5 Amazon orders have not arrived on time. I hope this won't become a normal thing.

Good product for what I require

La compre un poco renuente, pero superó todas mis expectativas. Ahora ya no tengo que cargar con mi pesado equipo de oxiacetileno, solo con antorcha de gas map (turner) soldadura y fundente. Los acabados después de soldar quedan super limpios y la oxidación es minima y en la mayoría de los casos es nula, en otras palabras, super recomendado.

Good Solder

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.
