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

Update: After two years installing our 4 ton AC Unit with Stay Bright 8, it has worked great, no leaks, all good.

Worked great to connect AC copper lines to the condenser and the evaporator

Great product s

The price little bit high, but quality its best.

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.

Price was good and products speak for themselves,

Expensive but well worth it. Flows like water. Used on new R410 A/C install. Use flux sparingly and copper must be clean. Should be sold in smaller quantities.

Just what I needed!

Works great. Easier than brazing and super strong. Used to fix a spot on my condesor where aluminum met copper. Patched the copper without melting the aluminum. So happy how easy it was to work with

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.
