I’ve got two pin lock kegs that seem to be of different makes. On one, the gas disconnect makes a nice firm seal when I attach it - it’s actually takes a fair bit of pushing to get the collar locked onto the pins.
On the second, the disconnect goes on easily, and has a lot of wiggle. I can also push it straight down a good 1/8" - 1/4". If I apply pressure I can also hear gas escaping with even a tiny bit of sideways force applied to the disconnect.
Is it possible that there are different kinds of pin lock posts that require different disconnects? Or is it more likely that I have something like a broken post?
UPDATE: It’s the disconnect. I’m not sure exactly what’s wrong with it, but I just thought to try swapping the gas lines, and now it’s the other keg I can’t get a good seal on.
