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

I used this to solder a leaky line dryer connection on a HVAC line set. The nice thing about this stuff is it works on copper and steel and does not require a lot of heat to work. It also has a very high tensile strength. This stuff works with a regular propane torch (not MAPP, or turbo, just regular old propane) and requires a lot less heat. The only downside is you have to clean and flux the copper or steel and it takes a bit longer to heat up than oxy acetylene, but 5 minutes of sanding is better than having to purge your line or open the system up. This stuff flows really well with about 30 secs of heat from a propane torch. Its also very strong. Its not cheap, but neither is brazing rod. Unlike braze, this can solder steel too.

Used on my a/c lines when I replaced my condenser

Great product s

This combo order is by far the best I’ve found on the market,

Product as described. Works well.

Super expensive but works great. The unusual melting point really helps to seal big gaps. Rated to 10k psi so it will last forever on hvac lines set sweating. To seal big gaps just heat the coupling above melting point and apply the solder. Once you think enough of the joint has solder then remove the heat and keep pushing more solder in. Soon it will thicken and fill the gaps.

Made the job much easier!

It is a great product

Items are easy to use. And are as advertised

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