Beer quick disconnect leaking

It was on the correct post (since I expect that question).  I went into the garage as I was heading to work and saw beer on the floor, then looked in the fridge and saw that beer had been seeping from the top of the QD. I disconnected and turned off gas (simply because I didn’t have time to troubleshoot). When I got home, I was relieved to see that I still had some beer in the keg and gas in the canister, so it wasn’t a total disaster.

The night before, I had taken apart the quick disconnect and cleaned it before reassembling and attaching. I’m embarrassed to say I had not cleaned the QD before–I only recently realized it could be disassembled. I’m guessing I reassembled it incorrectly–too tight? too loose? I have another new beer line QD in pristine packaging that I’ll swap in.

So… when I clean and reassemble this QD… what am I looking for? How do I ensure it won’t leak?

There is a small square oring below the cap. It can be a hassle to get in the right spot. I prefer to put the ring in the body and then put the cap on.

Double check and be sure you have tightened the top well. Also be sure to check that your swivel nut (if you have one) connected to your line is tightened enough as well. I once brought a full keg of beer to a party and had a small leak from there that I just couldn’t pinpoint for the longest time. It took a drunk buddy of mine to show me that I was a complete, blind idiot. Unfortunately, I have not changed much.

Make sure you didn’t put that plastic pin thing in upside down.

When I opened it up yesterday, I took out all the parts and noted that there is a gasket under the o-ring that was deformed, probably from when I reassembled the disconnect. I took it apart completely. I have a couple more of these so if nothing else this one was sacrificed to scientific discovery. Thanks for all the tips.

Live and learn.
