Unlike standard lid O rings which have a .280" cross section, our exclusive Overside 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.
