    My GX CS4 filling guns, but will not fill my scuba tank.

    Lol, I got one of those and since I'm so used to my other valve where I need to turn the main knob to fill, I opened the valve. Well, of course the valve should remain closed - that one's 8mm plug is one way, so you keep main valve shut. Not saying that's your problem but I felt a little silly...

    Tank fill valves on AliExpress

    My gx is pumping away right now, lol. I have gone from 0 to about 2800psi in like 4 shifts because I don't want to overheat it, and was too lazy to get out the old yong heng. Fill is via one way check valve, which I like better than my old valve where I had to open the knob manually to fill...

    Tank fill valves on AliExpress

    I just bought more or less the top one off Amazon, iorman version looks same. Seems ok, I am filling now so I guess I will see soon if any leaks. Not premium by any means but should be sufficient.

    Double cylinder air filter burst disk/cutoff

    I have one of those double cylinder air filters from Tuxing. They rate it as 300bar/4500 psi which.. isn't a thing lol. Anyway, as the little release valve on the side starts releasing air at 4000psi or so, I can't fill anything to 4500psi. I'm thinking of just plugging the hole with a dead...

    GX CS4 compressor

    Got my CS4 in a few weeks ago, and have used it a few times to fill large SCBA tanks. So far so good, seems to work great, no leaks, doesn't seem to get too hot. I have a completely empty tank I am filling and I'm doing it like 100bar at a time just because. Is it better to run it e.g. 3 times...

    recommendations

    I'd say it depends on what you want to do.. If you are thinking fully auto BB, the Umarex M1a1 seems to get the most raves around most of the forums I read on, I'm considering picking one up myself but that MPW seems pretty nice too. For more leisurely plinking or pesting, I'd pick a .177 or...
