tell me the flux mixture you used

[cagrigurbuz]

flux is 040 mixed with water

[error204]

@cagrigurbuz tap water?

[cagrigurbuz]

@error204 pure, distilled or demineralized water

[appapo3]

I would be interested to see this work on an old system where oil penetrated the pores of the copper and aluminium

[cagrigurbuz]

oil should be cleaned before brazing.

will joints like these last a decade or more if submerged in boiling water? I'm looking to build a solar hot water heater...

thats not brazing..its just soldering..yes both are close to the same thing, but if you use solder then its soldering..lol still a good video but a little missleading. the two main differances between the twoo are 1. temp, (solder melts at a really low temp, almost like lead, in fact you can solder with lead as well) 2. when soldering all you have to do is touch one place on the pipe and it will flow all the way around the pipe "soldering it" with brazing you have to slowly work it around.

How much pressure can the joint handle?

Will it hold up to the new 410 pressures for air conditioners?
