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

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.

Price was good and products speak for themselves,

Just what I needed!

If you’ve ever soldered copper, this is the way to go.

The solder melts as expected and the flux flows.

Work as described use it on my air condition works great

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.

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

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

Very easy to use! Much safer, faster, easier, and cleaner than brazing! Hands down the BEST silver solder on the market!
