This American made, pressure relief valve assembly (with new valve) will allow you to fix any keg lid. If you have a plastic "Dome" style lid you simply remove that valve assembly and install this one. If you have a different style call us and we will help you determine how to fix you lid! Call 512-805-3300. This will work with Ball Lock or Pin Lock, Standard or Racetrack and all brands. It includes a replaceable valve so you never have to worry about having having a non-repairable lid in the future. This valve assembly has an o-ring on the bottom as well as a sanitary o-ring that will not allow liquid to get into the threads. This valve assembly is metal, not plastic, so it should last a lifetime! We also offer these lids at bulk pricing if you need to repair a lot of lids. Call us for pricing for 10 or more.
