Any sure why to tell the difference between the gas and beer posts on a ball lock keg?

I took my one and only ball lock keg apart awhile back and when re-assembled it, taking a guess on which post belonged on the Gas/In side and which post belonged on the Beer/Out side. I could not remember which post went where but also did not see any obvious differences between the two posts. Now I'm getting close to filling it and want to be sure.

I know the gas post and the beer post are supposed to be different...thanks for any help!

i believe the beer out post will be about 1mm(or less) larger then the gas-in post.

(if you've ever accidentally put the gas-in on the wrong post it's a bit difficult to remove)

Often, the gas post will have nicks in the fitting just below the o-ring.

On all my kegs it is pretty clear what's what. The gas post will visually just look a little different. A notch here, a line there, etc. Something that makes it easy to tell (without having to measure 1mm).


Man I'm slow...

This would have been good to know before I pressed the wrong one on. I did manage to get it off again, but it was surprisingly difficult.

Thanks to everyone for your help! In looking at it again, I did remember that one of the posts had those notches, but I didn't know it the notch was for the gas or the beer. Now I know!

Look at the first "ridge" down from the top of the post.
Gas In post have a small ridge. Liq. out post has larger ridge.
