Brass drain tube part 2

[steplift20]

I was watching on you tube and what this guy did was heat up to cherry red the end that is not flared after it was red hot he put it in water than installed it, he said it makes that end softer so it bends easily. Is that the way to do it?

The term for this is annealing. When brass, or copper, is worked it gets "work" hardened. The only way to bring back the original soft properties of the metal is to do just as you described - heat to cherry red then let it cool, which softens the metal. So yes, it would definitely bend easier once it is softened.

look up annealing brass, plenty of re-loaders use it to form case mouths. I was incorrect about quenching, apparently brass does need to quench after heating. But you don't need to get it red hot, recommended temp is 475 degrees F

Thanks for the replys

I'm going to replace the brass drain tube and a read somewhere to use 5200. I think a marine sealant like 4200 or something in that category should be better cause 5200 is permanent, what do you think?
