The grey (gas) disconnect attaches via a swivel adapter to our mini regulator and fits onto gas posts (marked with a line) on either the "Missionary" or "Double Ender" spears and carbonation caps.
The black (liquid) disconnect attaches to the MFL tap shank adapter for connecting a tap to the liquid post of the "double ender" spear. The black disconnect can also be used to attach gas to the liquid post in order to force carbonate home brew more quickly.
I wanted to connect my mini CO2 regulator to a 5/8“ flathead keg adapter and was quite confused. Normally, you call support and have to wait minutes, with press this and that and if at all, you get through, you don’t get what you really want. It’s so extraordinary and surprising to get such quick response from support and real help through pictures and suggestions. Simply outstanding. Now, I had one of the owner on the line. But, if the owners take such interest in their customers, it’s but logical that customer satisfaction is quite high on their priority and the employees get it too.
