Default are corny lid vents easy to replace?

I have 3 lids like this:




I want to have lids like this


or like this




I'm assuming these are stamped or cast 304 stainless lids. Anybody ever mod these? I can weld them easy enough, but was thinking of simply machining them out and replacing them with a swagelock pressure release that just screws in.


Any suggestions? One of these?

i can tell you the one on the pin keg with no discons attached when the nut cracks or the thing leaks, no longer available. the bottom style is ~$8 for it. drawn 304. i have thought of just welding a plate on all of mine since i can't fill the ~1 1/4 hole with any other style relief valve.

I think the best option is to replace the entire lid. Unfortunately, the lids are pricey and somewhat elusive. I've got a couple of kegs with the "dome" type pressure relief valves which are no longer available. They are still holding up, but one of the nuts is partly sheared off, so it's just a matter of time before I will be having this same problem. My ace in the hole is that my friend came across a bunch of abandoned ball lock kegs and I may be able to cannibalize some of them for parts. I like the idea of patching the hole by welding a plate over it. You'd think the chinese would come through with some knock off keg parts and help us out. It should be a slam dunk for them to crank out some lids and such.

Looks like it'll be welding then. I can keep the heat down enough to prevent warpage I think. Looks like the easiest thing will be to take the whole valve section out with the bridgeport and weld in a pre-machined insert which will accept that screw-in valve pic I showed earlier.

Would still like to hear any ideas I might have overlooked.

Thx guys.

Would this item from KegConnection.com help

Pressure Valve Replacement Click on the description tab. They say if you call them with your issues, they will consult with you to help fix your valve issues.

They are also good to deal with. Normal disclaimer, don't work for them or gain from them

Hey! That's perfect. Thanks. Some work might still be necessary due to the size of the current installed valves/vents, but this is exactly what I had in mind.

Well, i looked at the link. It said on some of them that you should assume they leak or do not have the valve installed. So um... why buy them?

hmmm, good point. They must have had others available last time I looked. Looks like the kegconnection might be your best bet then, unless you can find someone selling good lids. Looks like for $8.95 you get a weldless fix which you could weld on if you wanted. I should have grabbed more last time there was a pile of kegs at the scrapyard. I bought a couple for spares from kegs that had already been banged up.

Could you use this one so you don't have to work on the others?
