Stupid noob question - gas vs liquid posts
« on: June 08, 2013, 10:15:26 AM »
Are these really different? When I took my keg apart to clean I never bothered to note which post went where. Now I see that these are sold as gas or liquid side. Did I just get lucky when I put it back together?

Yes, they're different and yes, you got lucky.  Generally, the gas post will have a horizontal slot, star shaped base, or some other subtle marking.

If you get the gas on the wrong side you'll start asking yourself why your CO2 tank emptied so quickly!

Not such a stupid question.  I've rebuilt who knows how many kegs and an empty I pulled off the shelf morning had the posts reversed.  I did not notice until I went to pressurize it.  I hooked up the gas based on the post type, not the labels on the keg, and it sounded like somebody blowing bubbles.

You always have to watch which one goes where.

Unless you really used some elbow grease, one won't fit on the other type.

Please do not reply if your an evil alien!

Groove, "G", equals gas. Blank, or "B", equals beer.

I now buy o-rings of different colors and use them to more easily differentiate between the two.

Yes. The posts are slightly different diameters. Not enough to be obvious, but enough to make you curse if they're backwards.

Also the lip that the connector latches onto is bigger on the beer side than the lip on the gas side.  That's what makes it impossible to get it back off.

On a related note, if you have multiple kegs to clean, it is best to disassemble, clean, and reassemble one keg at a time.
Sometimes the posts and/or other parts from one keg do not fit on another keg.
Speaking from experience, this can be aggravating!

Excellent idea using colors.

Black or Blue for Beer is a good idea
Green for Gas might keep with the "G"/Groove/Gas theme better than red tho

My ball lock kegs are marked on the rim as "inlet" and "outlet" or something similar.  I use black o-rings for beer and red for gas, which matches the red gas line.  For the quick disconnects I use "black for beer" and "gray for gas."
