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.
I purchased one of these oversized gaskets to fix a leak in a pin lock keg I purchased (PRV needed to be replaced too). A normal sized o-ring for the lid did not fix this problem, even with a lot of keg lube. I would try to reseat the lid multiple times and what not with no success. I even tried a new keg lid that I had from a new keg I recently bought and it still leaked around the new regular size o-ring.
Once I received this oversized o-ring and placed it on the keg lid with some keg lube, problem was solved! Now I am kicking myself for not ordering more to have on hand if I source more used kegs that may exhibit the same problem!
Thanks Williams Brewing for a great product!
I had a keg lid that was leaking around the o-ring and lost a entire canister of CO2. I tried bending the keg lid legs but was unable to even get them to move. I tried some gasket lube but it wasn't enough and thought the only option left was to buy a new lid but then I came across this product. It did the job! I put the seal on, pressurized the keg and tested it with the Williams pressure tester several days without any drop in pressure. Thanks for carrying the best keg parts around!
I bought a used 10 gallon keg to do primary fermentation in and found I couldn't get it to seal. I tried everything, excessive keg lube, nickels under the feet and banging it with a hammer. Then I found these and it sealed right up and has been working great for me!
This is pretty awesome. I found it shortly after a CO2 tank emptied unexpectedly. This did the trick. No more worrying about a proper seel.
Bought some used corny kegs with slightly damaged top fittings. Oversized rings did the trick!
