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.

Pros: The larger diameter O-ring with a softer compound does a great job of sealing hard to seal kegs. I have 3 of these now and could use 3 or 4 more.

Cons: More expensive than the regular lid rings, but well worth the price. These should be included in the kit of a complete set of rings.

You will never buy anything else - guaranteed!

Pros: No leaks at any pressure. No grease needed. Awesome. Eliminate major corny keg headache. I rebuilt all my corny's with these o-rings. One is paid for in one lost tank of CO2. I love them and would not buy another. Tossed my "normal" o-rings in trash. Would not even consider giving away after discovering these.

Cons: Wish more people would wake up and buy to bring cost down!

O Ring is perfect for my cornies

Great product..Fixes any or all lid sealing problems. Bill

Does the job, a bit pricey

Review by colin on 11/1/2012

Fixes most leaky lids. Not a miracle worker -- lids with really bad leaks will still need to be repaired. I ferment in corny kegs, so the pressure is low. Most kegs (most of mine anyway) need higher pressure to seal with conventional rings. This fatter o-ring usually creates a good seal at atmospheric pressure, warding off oxidation and contamination. For what it is (just a larger diameter o-ring), this product is a bit pricey, especially if you want to replace the o-rings on dozens of kegs. That said, I haven't been able to find them anywhere else, and making my own from cord stock didn't really work out that well. So I'll pay the $5!
