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.

If you dont want to mess with oxy-acetylene on copper connections then this is the kit to have on hand. You can find all kinds of positive reviews and uses of this in HVAC connections as well as potable water because its lead free. No need to flow nitrogen because it can be used with Mapp gas. Very happy.

Just what I needed!

Price was good and products speak for themselves,

The price little bit high, but quality its best.

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

The solder melts as expected and the flux flows.

Product as described. Works well.

Expensive but well worth it. Flows like water. Used on new R410 A/C install. Use flux sparingly and copper must be clean. Should be sold in smaller quantities.

Great product s
