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.

didn't work for me.
the o-ring i received didn't look much (if any) thicker than my old ones. it didn't seal any better, either, so i'm back to doubling the sealant grease.
Very Useful
We produce our own maple syrup. We use corny kegs to store the syrup as an alternative to 5 gallon buckets. Unfortunately, some of the kegs we come upon have minor leaks which is unacceptable to us. These oversized rings are just what we need to solve the problem and let us to store our syrup properly. Thanks for the help
Oversize O Ring
I like to ferment in corny kegs. These O rings reliably seal the lid without the need to pressurize the keg. They work great.
Must have for old kegs
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
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,
