Default Corny wont hold pressure - what to do?

I have a corny that has some how developed a leak and I think it is in the main seal, it might be out of shape and not able to get a tight seal.

My question is what have others done with out of commission cornies?

I have several of those kegs and just bought the O-Ring kit for them and that took care of any leaks. The kits are like a few bucks from any shop

I have replaced all the o-rings, the only thing i havent done is the poppets (which are on my list to change and check). But my real question is, is there a DIY project for out of commission cornies? Not necessarily, how do you fix it, but what can i turn this thing into...lol

So you don't know where it is leaking?

Have you sprayed all the possible leaky spots with soapy water to see where you get bubbles?


Also, basic question but did you lube up all the gaskets with keg lube when you replaced them?

My .02, new seals tend to not form to older Corny kegs very well. I have found that when mine has leaked like that a quick fix was to crank the co2 up to about 30 psi for a short period of time. The added pressure pushes the lid to the top and causes the seals to "seal" better.

Might try that.

Using new O-rings and some keg lube worked for me in the past. In your case it maybe old weak springs on the poppets in which case would need to be replaced.

Make sure to bring your old ones into the LHBS to get new ones as different manufactures have different sizes.

Good luck!

Umbrella stand, burner shields, planter, storage, funny metal hat, steel drum for a calypso band.

That's what you requested. But if it is the main seal, they do sell extra fat o rings for that issue as well as generous slathering of keg lube and also some spacers under the keg feet or reforming the metal bar that holds the lid on, etc.


almost forgot - 5 gallon fermenter is a good use !

I'll try that...I really didnt think about the new seals needing to be "broken" in but it makes sense...

and I always use lube! lol
