I'm using the stainless quick disconnects (QDs) from MoreBeer. Most are ok, but some of them are so tight, I can't make a locked connection no matter how much I push.
I assume it's the o-ring. I remove that and they click in no problem, light as a feather. Re-insert the o-ring and no can do. Is there a way to quickly break these things in? Maybe leave them locked together for a few days?
