Annoyed with 2 of my kegs, c02 leak

So I go to pour some of my Hefe, and nothing comes out. I'm like great, the line is froze. Nope, no c02 in the tank.

2 of my kegs, the c02 ball lock connector has to be on just right in order for no gas to come out of the ball lock area. It's like if I press hard down onto the connector, I can hear some gas escape. This doesn't happen on 2 other ball lock kegs I have.

Any ideas? Replace the post gaskets?

TIA
Justin

Yes sounds like new gaskets are needed.

Sounds like the o-ring is damaged - or under-size. A QD should not have significant wiggle...

Cheers!

New o rings and some keg lube should fix it.
