How do i remove odd shaped Corny keg gas post?

I replaced all o rings on 2 Corny kegs, but don't know how to remove the oddly shaped gas post like the one in the attached file.

It's a 12 point. I was perplexed first one I had. I have a wrench, I will go look.

It's probably 7/8", but you need to have 12 points instead of the usual 6. This wrench fits all ball lock sizes. The other side is 11/16". Not sure if a keg post comes in the 11/16" 12 pt style. I checked the wrench on the only one I have like that.

Definitely 12 point 7/8". With one of those and an 11/16" wrench one covers all the bases (11/16" posts are always 6 point)....

Cheers!
