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

Used this instead of brazing my ac lineset. With this, there’s no need for flowing nitrogen while soft soldering. Used on a 410a system and holds up to the higher pressures just fine.

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

I used the Stay-brite 8 to fix a leak on my mini-split system and my friends mini-split system too. The mini-splits were leaking where you release the R410a refrigerant from the pre-charged compressor (there are 2 set-screws you back out after you put the system together and vacuum it out). The system is supposed to seal itself with an o-ring in the set-screws that tighten up against a small shoulder. Both of our systems leaked and from what I can see around the internet it is not uncommon for this leak to happen on this type of valve after some time. We took out the set screw (had to remove the retaining ring first) and the removed the o-ring from the set screw. We cleaned out the set screw and fitting, fluxed up the fittings and screwed the set-screw back in about 1.5 turns. We soldered the set screw in place with the Stay-brite 8. Even though only 1 of the 2 set screws leaked, we took apart and soldered both since the system was without a charge. Both systems have been running perfect for about the last 2 months without any loss of charge. Perfect solution for an annoying problem.

The solder melts as expected and the flux flows.

Price was good and products speak for themselves,

Great stuff. Worked well, pleased with the results!

I tested this product by connecting two six inch length of 3/4 copper pipe. Fluxed and soldered them in seconds. I then cut the connected pieces lengthwise to inspect the joint and look for oxidation. No oxidation occurred and the solder join was completely and uniformly filled. Ive used this product on several a/c connections with excellent results.

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

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

It is a great product
