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

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.

Good product

great stuff

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.

Love it! Makes my job way easier as an HVAC guy when I need to do dryer replacements

Items are easy to use. And are as advertised

Great product s

Ez to use, hard to find videos on This but they are outhere. Take a couple of practice pipes before you do the job, the most common mistake is overheating. Soldered all my repair on the ac no leaks, vacuumed the system and hold without loss for one hr. I love it, will buy again when I need it.

The solder melts as expected and the flux flows.
