ok! so i discharged the extinguisher and filled it to the top with water and then put 150 psi presssure on it and left it overnight
no pressure drop or leaks
since i will not use it at higher pressure then 100 psi, i would consider it safe

thanks to everyone

thanks
the outside looks good, i will discharge it shortly

i bought a 9.5 liter water fire extinguisher it is still sealed it is proof tested to 500 psi the gauge is at 150 psi, it sais "overfilled" (90-110 is the green zone) the sticker on it sais it was last inspected in 1988( :shock: ) so is it still safe to handle, and if so, what could i use it for? i ...

why did you make it a private video

according to the DOT specs, Steel 72 scuba tanks rated at 3000(!) psi must have a minimum wall thickness of .164 (0.42 cm)at manufacture, but tend to run thicker, say, .180(0.46 cm) or so. You can't ignore overall diameter in talking about pressure capabilities. It might have thicker walls than a S...

1 cm thick walls???? That would easily hold whatever a fridge compressor can put out! according to the DOT specs, steel scuba tanks rated at 3000(!) psi must have a minimum wall thickness of .164 (0.42 cm)at manufacture, but tend to run thicker, say, .180(0.46 cm) or so. so i wouldn't worry about a...
