This simple but effective item is the heart and soul of keeping your purified water contained. This 55mm crown or snap-on light blue cap is the industry standard cap for 3 and 5-gallon water bottles. Its standard integrated cup seals both the interior and exterior of a bottleneck. The release tab on the outer edge makes removing the cap a breeze. The cap fits both glass and plastic 3 and 5-gallon bottles with a "Crown" or "snap on" top. For reference, the outside dimension of the bottle opening would be 2.165 inches. If you currently have a snap cap for the bottle, the outside dimension of that cap is about 2.75 inches.
