I have a 10 gallon cornie with a stripped thread on the out post. Any suggestion on how to fix it or who to take it to?  Thanks

If you can find a die that size it might be possible to clean the threads up, but I have no idea what the size and pitch is.

Check this listing and see if you can identify it:

A jeweler’s file might clean that up.

I certainly do not want to add insult to injury but exactly how did this happen?

I have a 10 gallon corny.  Unlike my other kegs, the gas and liquid sides have different threads. And there's no other indication of which side is which.  I can see someone who didn't know that just bearing down and wondering why the post won't go on.

You wasted $25 bucks.  The threads are galled.  This is a typical occurrence for stainless steel if not handled properly.  You can file it as one brewer suggested, or you can tap it again as another brewer suggested.  But the bottom line is the threads are cashed and will never be as strong as they were intended to be.
All good things come to those who show patients and perseverance while maintaining a positive and progressive attitude. :-)

And now you know why a $325 item was going for $25.  Scrap value on ~18 lbs  of SS is probably $4-5, so you can recoup a bit.  Just not like the cagy seller.

I would try cleaning the threads up as suggested. The required clamp load is not that high, there are a couple of undamaged threads that will support that load.

If you can find a die that size it might be possible to clean the threads up, but I have no idea what the size and pitch is.

I knew it was messed up when I bought it.  The seller was completely up-front.  I went in with the assumption that if I couldn't fix the threads, maybe try  welding a new adapter on it if feasible vs using it as a fermenter if I cant.

Thanks everyone for your insights.

I disagree. The top thread is the only one boogered up (probably caused by someone trying to put the wrong fitting on). Straighten that up and she'll work like new.

Es possib'le. And it might help get the die started too.

The keg was a Challenger VI, and when I found the right out QD, it fit like a glove.  Holds pressure just fine.  Thanks, I owe you a beer!
