I tracked this answer down on another thread regarding the same issue. and I'm thinking I am going to track down some green o-rings. thanks for the replies guys.
I have similar leaky post problems when disconnects are jostled slightly. My liquid lines are also subject to the leaks that come from slight jostling of disconnects. what did you find to solve your leaky post/disconnect problem?
I have a similar leak problem with pin lock kegs that I also picked up from keg connection. If I twist either gas or bev disconnect the leaks come on strong. What did you find to be the problem with your system? I replaced all of the o-rings with new ones from keg connection. no dice on...
