I ended up with this small corny style keg as part of a larger equipment purchase. The keg has no markings to help with identification. It holds 2 gallons and has typical opening. But the connections are odd. The outlet is standard Pepsi style disconnect with dip tube. The inlet though appears to be some type of gas quick connect. Smaller than air compressor hose style connections though. At this point the keg is kinda useless unless I can come up with some inlet solution. I’d guess the threads at 1/4” but not sure.
