Keg Quick Disconnect Internal Replacement O-Rings

cmbecker ball lock

Ball Lock and Pin Lock Keg QDs have an internal o-ring gasket that keeps liquid and gas from leaking out the top side.

I’ve found that it’s pretty easy to lose these.  Beyond that, they wear out and crack.  I’ve also had some that have gotten seated incorrectly and ended up becoming mis-formed so that they no longer sit properly.

This post is a look at a non-OEM replacement option, that I’ve found works well in standard ball lock style QDs.  They may also work in pin lock QDs, but that’s something I’ve never tried.

Silicone Dash 013 o-rings are not OEM internal keg QD gaskets, but in my experience they have fit in all the ball lock QDs that I’ve tried.  Your experience may vary.  These are relatively inexpensive, that means it’s easy to have spares on hand when the need arises.

Recommendation, Use Food Grade O-Rings Here:  This o-ring probably has the most contact with your beer.  It touches all beer served and has extended contact with beer sitting in the QD between pours.  In my opinion, it’s important to use food grade materials here.  More about food grade o-rings
