I have a Cornelius Co. keg (no specific 'model' stamped on the keg). The posts look like 'type A', which wouldn't be right for a Cornelius Co. keg. (I think 'A" is for Firestone?) They look like Type 'A' except that the gas post has a 12-pointed star shaped 'nut' instead of a hex. I removed the gas post and tried (gently) to replace it with a Type 'A' gas post.. it only went on a turn or two and got stuck. Any idea what this 12-pointed-star-nutted post is? TIA!
Well, I knew it was a gas post. But my point is that the post is the size and shape of a Type A gas post. And when I tried to replace it with a Type A gas post, it would not fit. So what type could it be? (It looks nothing like a type B.)
