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.

Must have for old kegs

Review by Jeff Adelsberger on 1/22/2021

These are great and just the thing for stubborn kegs. Worth the premium, just got a bunch to out fit my kegs again. Plan to use these on my keg fermenter.

Over Sized O-ring

Review by Dennis on 12/14/2020

Took care of the leak that developed around an old keg that my buddy found on the curb for trash pickup. The softer wider o-ring was all that was needed to seal the keg and hold pressure,

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

Review by John on 3/13/2020

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!

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.
