Unlike standard lid O rings which have a .280" cross section, our exclusive Oversize O Ring has a slightly larger (.310") diameter, and is molded from softer rubber, for a more positive seal at low dispensing pressures. An ideal fix for an older keg with a leaky lid, or for any keg that needs to be pressurized before filling to achieve an airtight seal. Fits all brands of kegs, pin-lock or ball-lock, with a 3 by 3.5” clamp down oval lid. 

Best for older lids, as new lids when installed on older kegs tend to have tighter tolerances, and a standard O ring (our part P92) works fine. Note: Pictured lid is not included.

Stopped co2 from exiting leaky keg
While these look just like a regular O-ring they are ever so larger which worked perfectly for me in some kegs that I was unable to use without these.  Highly recommended.

A must have for older keg users
I had a couple of old Cornelius kegs laying around that no longer sealed properly. Instead of chucking them, I decided to try these and I was very pleasantly surprised, they fixed the issue. I recommend these to anyone with keg leaking issues, they work!

Oversize Keg Lid Sealing 'O' Ring
Fantastic product. A perfect fix for a couple of my older kegs that began to have slow lid leaks. I will certainly be purchasing more.

Oversize corny keg lid O ring.
A face-lift that will extend the life of my kegs and save me money on CO2. Highly recommend.

Seal with no pressure
These gaskets are amazing and seal with no CO2 pressure.  The only problem with the two I received was that they gave off an extremely strong sulphur smell when I sprayed them with Starsan (they were first cleaned with PBW).  The smell went away after a 20 minute soak in Starsan.  Apparently whatever chemical that was reacting with the Starsan was used up during the soak and they now give off no odor.  I feel like this should be mentioned in the description so nobody ruins an entire keg of beer.
