They’re made in China, are actually super low carbon recycled steel, sometimes cast so poorly they are square, and have a pressure rating of 150psi, although I wouldn’t trust them much past 60-80psi.

Think of them as black pipe’s DWV…

So you trust pvc move then black pipe? , anyways I think ill have to keep this at a 5x-6x mix due to my ignition witch is only a peizo, might have trouble sparking at higher mixes, I should get healthy carnage results

I've used the malleable iron fittings at 500 psi, but I don't advertise that as being safe, and I have no idea how close it is to their failure point. The only one of those on my hybrid is the union, and I really don't care if that fails, as I'm getting a 3000psi one from McMaster in a few weeks anyway.

I definitely wouldn't take this hybrid to 15x unless I was a long way away from it.

And where did you get that ball valve? Even McMaster doesn't have brass ball valves rated that high.

Well i take them to 350psi regularaly and im doing fine, no BOOMyet


edit DYI beat me to the malleble iron high pressure thing

I actually have no idea where the valve came from, my dad said he got them from a hydraulic factory place where his friend works and he just gave me like two of them since he knew I was building something that required high pressures.
I think this website I just found may be helpful about the iron fittingshttp://www.engineeringtoolbox.com/iron- ... d_855.html

yeah I use them all the time and I take them regulary up to 30 - 35 bar...

but still we don't know how much they can take so it would be a good idea to check it

Well its not brass; its hydraulic carbon steel, but they are rated up to 7250 psi depending on size on mcmaster: part number 4715K15
