The Storz Adapter line is designed to adapt valves for fire hose connections. The adapters are manufactured according to NBR 14349 and 16021 standards and are available with 1.1/2” and 2.1/2” outlets.
 This adapter has a 5-thread female thread with a 2.1/2" gauge on one side and a 1.1/2" Storz-type outlet (quick coupling) on the other side, which is used in fire hydrant valves to provide quick coupling of hoses, reducers, and Storz-type plugs in fire lines.
