Oversize Keg Lid O-Ring from William’s Brewing.
About, from William’s: “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. ”
As of this posting, William’s Brewing is discounting these to $3.99 when you buy four or more. Check product page for current price and availability.
From HBF Reader David Says: “I have some of these for some Pin lock kegs that I used ball lock lids on that wouldn’t seal up. They are now some of my tightest lids and are great.”
Facebook Friend [Connect with HBF on Facebook] Gus Says: “These things are awesome. Fixed a keg that was headed for the scrap pile. All my kegs rock these.”
In most cases, Pin lock and ball lock cornelius style keg lids are interchangeable from a size perspective. That means you can, generally speaking, put a pepsi/ball lock style (manual prv) lid on a coke/pin lock style (no manual prv) keg. In my book, that’s a solid upgrade.
