But when you fill your tank, their pressure will be equal (The pressure is determined by vapor pressure of oxygen liquid at that temperature). At this stage you only fill oxygen gas. The second stage is usually continued by filling oxygen liquid by gravity or small pump. (I mean, you can fill your 200 psi tank with 200 psi source)<br><b>References : </b><br>Mech. graduate student Initially when your tanks is empty, the pressure of the source is higher.

When the pressure becomes equal you have no driving force.<br><b>References : </b><br> The gas moves from the high pressure to the low pressure.

If you are just connecting one tank to another you cannot exceed the pressure in the supplying tank. <br><b>References : </b><br> Not unless you have some sort of compressor to increase the pressure.

In theory you could achieve 3000psi in your container by heating it but that's not recommended.<br><b>References : </b><br> yes, you cannot go higher than 200 psi if all you have is 200 psi, you need a compressor to squeeze the gas (O2) up to 3000 psi.
