Because he is building a pressure pot for testing O2 sensors to 3 ATA.

Actually I only need it to go to 2 ata or so. :dork2: Filled slowly, and for short periods of time with no moving parts. A little different than a space suit. :wink:

your best bet for reducing compression ignition risk is to run the gas through a flow restrictor before it goes into your potentially unclean pot. I wouldn't overthink this just reduce the ignition sources and try to keep hydrocarbons away and you will be fine. I made a pot out of PVC pipe which is definitely not O2 compatible. I just restricted the O2 flow before the pot.
You originally said 30psi, that is where I got the 3ATA from
