These are the o-rings for the dip tubes on your standard cornelius kegs. They fit both the liquid and gas side dip tubes, helping to create a good seal so that your dip tubes function properly. If they start to fray or wear, replace them with these common dip tube o-rings!
All kegs have o-rings: one on each post, one on each dip tube, and a large closure o-ring that fits over the center closure. This is the large o-ring that fits over the lid, creating a seal that allows the lid to remain sealed in place. Over time, these o-rings can wear out. When that happens, it's time for new ones!
These are green pin lock tank plug o-rings for your keg. They fit on the tank plugs, or posts, on your cornelius kegs. When your tank plug o-rings start to fail, the disconnects are usually hard to get off and on, and the o-rings do not create the seals that they once did. A simple fix is to replace them!
