Nope. You'll have to come up with a better solution. You can't use galvanized, it will rust with a quickness. If your braid is collapsing from the weight, switch to a manifold.
Not to mention the toxicity of the galvanization. That alone is a deal breaker. I think it's cadmium that is the problem. Palmer talks about it in his book. Do NOT use galvanized anything in the brew system!
Third to say 'No'. You need a better solution. You could try running a length of well-drilled/slotted PEX inside your braid. It maintains structural integrity up to about 180 before it should start to soften a little. I've never hit 180F in my MLT.
I hate torching & welding the crap. bruva, use something else. galv ain't right. unless you like involuntary twitching & vomiting and possible long term brain damage. (I have no hard evidence of this claim)
There is a difference between pride and arrogance. Which do you hold in your heart?
