The Edstrom Original Drinking Valve is made of solid brass material with a stainless steel stem and a tough elastomer seal and diaphragm. This model has a 3/16″ barb connection for use with the Flex-Tube plumbing system. (The Valve Clip, 1100-0867-100, is normally used to secure this valve to the wire cage). A great valve for rabbits and chinchillas and other larger rodents.
