Alternatively, I'll buy a new hose. My measurements are that the connector is a left-hand 1/2" major, 13/32" minor thread, but that doesn't seem very common. Does Weber use non-standard connectors?
I just bought a Weber Genesis II and would like to use the butane cylinder and regulator I already have (the blue one in the image).
The clip on the Weber hose though is a type I haven't seen - any suggestions on how to remove it, ideally without destroying it?
