Hello planted tankers! I recently purchased an Intense Naito regulator, same as the atomic regulators only it has 21mm - 22mm threading (which is European Standard I'm assuming?) and it won't fit on my cga320 cylinder. It actually screws on but there's a small leak that is causing loss of pressure. Would I be able to use another o-ring inside the connection to prevent the leak?
Also, I've been searching for a converter or adaptor but I've had no luck. There's one on eBay but it looks like it's the opposite of what I'm looking for (it converts 21mm 22mm to cga320 threaded regulator) Any suggestions or help? I'm new to pressurized co2 so this is all very foreign to me.
