I thought they would fit 5 gallon Primo water bottles stored on their side but they don't work properly. Unlike caps that come with store-bought water bottles, they don't have any sort of liner or gasket in the cap, so water will leak out if bottles are stored sideways. Bottles VERTICAL, but not good if you store bottles sideways. They are great for Primo bottles and can be removed and reused.
