    Like the title says these smaller tanks are hard to come by, even if it is just the tank itself I have a few brand new on/off valves and can press into service I’m just having a hard time finding one of these anywhere in stock. Thanks

    Don’t believe they are I’m just aware they are a small operation and have been taking awhile with orders so I’m looking at other options seeing as I already have the on/off valves if I find some with the pin valves I can change them out.

    Sadly those are for gaseous CO2, not for liquid (as far as I could tell from looking into them previously)

    Never heard of a gaseous CO2 bottle. The rating is 3oz/80g and that weight of CO2 in a bottle that size is going to be liquid.

    Your video is co2 filling 101. The guys large tank had a siphon tube. He was pushing liquid CO2 into the smaller bottle. I've converted these 3oz bottles and believe me, they are standard CO2 tanks just with the oddball threading on the top. Replace that with a standard paintball on/off and your good to go.

    Converted 3oz Sodastream tank.

    And Ive filled paintball co2 tanks and you use a scale not pressure gauge.. since the liquid has a weight, not pressure. I was a paintball field ref for a few years (great way to support the addiction..) It only has pressure once it phase changes from liquid to gas.
    But ok.

    Correct. These tanks are rated at 3oz, a weight. So what is your issue with them?
