Charlie,
I have used these stainless steel water fire extinguishers at pressures up to
550 psi and hydro tested them to 700 psi...
https://www.firesupplydepot.com/fas-a240-e.html. I was told, but have not ;
verified, they fail at 800 psi. I have used them for LOX and kerosene. I did
weld a 3/4 NPT female weld bung to the top end and a 3/8 bung at the bottom as
shown in the link above.

Hi everyone,
I’m looking into some options with regards to the fuel tank for my liquid
rocket engine and would appreciate some advice with regards to the general
structure. As of right now, I am considering using a fire extinguisher tank
and modifying it with regulators, pressure release valves, check valves etc.
Is this a good (or dangerous) idea? And if so what is the best way to
implement it. I should mention I am not planning to deal with extreme
pressures as this is my first attempt with rocket engines.
Kind regards, Charlie
