Do I have swamp ass and how to identify it? Is this a shift in the brazing/nitro  policy? I wonder if it isn't a flux issue.

Since I was taught only braze 410a line sets due to the higher pressure. associated with R-410A systems means keeping moisture out is a must. Formulated to exceed the requirements for R-410A refrigerant … Yet, the heat required to melt the braze thins the metal around the joint. A flux is also required when using high silver braze alloys like Safety Silv® 45 or 56. If flux is used the flux will turn semi-transparent close to brazing temperature. Don't forget, too, that if you're using a line set that has been used with an R-22 system, it is imperative that you flush the lines to remove all the old oil. Most people prefer nitrogen from what I've been reading, but it is becoming too hard or too... DAN THE AC MAN has given you the correct answer. There's been the rare occasion on ref line repair when there was no way I was brazing; carpenter shot 5 16cc nails in our line set. Bonds in 3 to 5 minutes. I'm interested to see the answer to this too. Do not apply flux to the fitting socket. there was almost a fight on that job. The Highside® HVAC super pro bonding kit is the perfect solderless solution for bonding copper, aluminum, and brass, in any combination. Does anyone know of any mfrg's that allow this soldering policy? If I had my way I would braze everything. The units  are 13seer, r410a which I am going to pipe and start up .The factory engineer said that I could use a "refrigeration grade silver solder"{staybrite #8 ?] Easier to protect refrigerant valves with lower melting temperature than required to create a braze joint.

Brazing to make an LeAk-fRee ing line connections is no different. No nitrogen purge needed since Staybrite 8 melts at a lower temperature.

A brazed joint is strong no matter what if the silver solder penetrates the connection all the way around.

If the evap.

The burst rate of a brazed line set is 1800 PSI vs a silver-bearing solder burst rate at 3600PSI. I do braze fittings and line sets if buried in walls.

If this is a Trane commercial 6 or 7.5 I can tell you that these suction connections can be brazed. Copper Pipe fittings sealed using Silver-bearing Solder are stronger than a joint that’s been brazed together.

I was always under the impression that flux (same as in any closed loop system) will muck things up. You can sign in to vote the answer.

I burn wood, it smells good!

I don't think the pressures that 410 runs at have much effect on brazed vs soldered joints. Most manufacturers' installation guides recommend using "no flux" on copper.

Annealing occurs from heating the copper which causes the metal to thin. If you think about it, where do we most often see leaks? Thanks @ChrisJ.

If there's an obvious difference one side may require more heat. A Staybrite 8 joint handles more pressure than a Sil-fos brazed pipe connection. If you follow their rules, the layers will chase them first, since they have deeper pockets. The factory joints or coils may leak.

The manufacturers don't help us out much. I think I looked this up before and even the solder and brazing manufacturers agree. It looks like you're new here. That's just part of the expense of the business. The bursting pressure using stay brite is a lot higher than brazing because the tubing is not annealed.A TRANE technician told me the other day he stay brites everything and I was surprised to here that.One reason for brazing I have herd is in case of a fire in the building the stay brite will pop at about 550 deg and release phosgene gas where the brazing is good for 1000 deg or so.

I've heard that some still don't purge the lines if using a filter, bad idea? Still have questions? Staybrite 8 is a silver-bearing solder used on 410a line sets and if done correctly is better than brazing in many applications. From what I've observed all manufacturers, not some, ALL say to braze all joints while flowing nitrogen. I will admit it's been a long time almost 5-6 years. From my experience I find silver solder to work great on copper where a lot of stress from vibration or system movement will not be present. The potential problem is moisture can cause the breakdown of POE oils into organic acids. I mention if done correctly since acid flux shouldn’t be inside a refrigeration circuit. Also be sure to only liquid charge the unit if there is anymore refrigerant required. Has anyone tried that tried or heard issues with that Red stuff ? The phosphorus content makes these alloys "self-fluxing" on copper. Most are silver soldered and no inert gas is used. In some instances it was required that I use stay #8 instead of brazing the lines.

You can use Stay brite 8 solder. Only apply flux onto the pipe, not the fitting. I have used Staybrite 8 on many new r410a Air Conditioning installs without any leaks from the sweated together joints. If parts are overheated and flux is difficult to remove, mechanical cleaning may be required. For R410A, braze all the way. I silfos everything. When heated, flux liquefies and capillary action will draw it to the fitting. But I have seen factory connections that make me wonder ( Liebert ). You do not have to braze your lines. Most often it's flares or vibration that causes leaks from what I've seen. I've removed a fair amount of copper in both refer systems and hydronic systems. And brazed with nitrogen is the cleanest inside by far. This is a visual indication you are ready to apply the brazing rod. I've used it on number of jobs, 410a included, with no problems. It's the subtle vibration that makes Staybrite a poor choice as much as the flux. Braze rods are also available flux coated. NFPA 99 allows using flux coated rod on 7/8" or smaller dissimilar metal joints.

The coating melts during heating and flows into the joint ahead of the melting braze alloy. Always use a brush to apply a thin coating of flux and don't flux to the end of the tube. I know there is some controversy about this. Moving a system puts a lot of pressure on the joint. These braze alloys have a uniform covering of flux on the outside of the rod.
