Hi,
I'm preparing a keg for my latest brew (oatmeal stout). I have pin-lock kegs, and my usual procedure is to:
As I was flushing the sanitizer out of the keg, it started leaking fairly badly around the liquid post. I checked everything over and noticed that when I look directly down on the post, I can't see the o-ring on the post. The o-rings are pretty new, but I pulled out a replacement and noticed it's slightly larger than the one on the keg. I put the new o-ring on, and it fits a little loose (I can rotate it), but I retested with sanitizer and did not see any leaks. I assume the disconnects compress the o-rings when they are in place.
I can't imagine the universal poppets caused this issue; I think it's the o-rings. Is it better to have an o-ring that shows a little from the top, as opposed to one that's so tight it doesn't show at all? I have an o-ring kit, and the two seem to be only one size apart.
I usually carb my kegs before I put them in my keezer, especially with beers like this that are going on a nitrogen tap (I put them on CO2 arount 8-10 psi). So, I'll have a week to keep an eye on it before it goes in the keezer. I have a short transfer line, and I'm planning to put two disconnects on it and attach it to my liquid line, just to test for any leaks while it carbs.
What are your thoughts?
Thanks for your help!
I'm preparing a keg for my latest brew (oatmeal stout). I have pin-lock kegs, and my usual procedure is to:
- Sanitize everything.
- Assemble the keg, using keg lube on all the o-rings.
- Fill the keg with some sanitizer and roll it around to coat everything.
- Hook it up to a CO2 tank to flush the sanitizer.
- Fill the keg.
