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

Ok

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.

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.

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.

Product as described. Works well.

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

Great pice and Harris quality

Price was good and products speak for themselves,

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.

Ok...you are supposed to Braze using an N2 purge to prevent the contaminants inside the lines. No longer a problem. This melts at a much lower point yet yields a stronger connection without the annealing of the copper lines so they dont get soft. Watch a few vids before attempting. Try out on a few joints before tackling your ac lines. Not exactly the same as sweating with standard solder but close. Worked like a champ and my Heat Pump is working great. no N2 required. No oxy/acetylene. Just Mapp gas required
