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

Great stuff. Worked well, pleased with the results!

I was skeptical that a solder could be strong enough to hold up to 300+psi of r410a, but heard good things so I gave it a try. Ive used it on several residential AC installs and it has been flawless, less leaks than brazing and wayyyy faster than brazing. You have to use Emory cloth and/or wire brush to clean the fitting very well and use less flux than you normally would with plumbing solder, just make sure to use flux on the male fitting at least. It has been a complete game changer. Instead of hauling around a heavy ass welding rig, I can just carry a 5 pound map gas torch and get it all done fast! I will be sticking with this if all proves leak free in the long term.

Items are easy to use. And are as advertised

The solder melts as expected and the flux flows.

THis is a great combination. The Solder flows really nicely - heat it gently, and dont get the flux too hot. It works great with a Propane torch, just take your time. I really like this. I use Hard solder and MAPP Gas for material that will stand a Glowing Red heat, but this stuff works great at temperatures just a bit higher than lead solder.

Having never done hvac line sets before I thought I’d give it a go… this was so easy and saved me so much money compared to having a hvac tech come braze lines… it’s been 5 months since I used the silver soldier on my line sets and it’s holding strong.

It is a great product

The price little bit high, but quality its best.

Ez to use, hard to find videos on This but they are outhere. Take a couple of practice pipes before you do the job, the most common mistake is overheating. Soldered all my repair on the ac no leaks, vacuumed the system and hold without loss for one hr. I love it, will buy again when I need it.

Love it! Makes my job way easier as an HVAC guy when I need to do dryer replacements
