The Eheim Double Tap Connector allows you to control the flow of water passing through your hosing, and shut it off completely. Simply adjust the two ball valves, and disconnect the hosing from the center to remove your pump or filter for maintenance without the headaches of excessive water spills, or fumbling with messy hosing assemblies. Heavy duty connectors seal snugly onto hosing with barbed ends and plastic lock nuts; internal disconnect assembly features a rubber seal ring and threaded connector to prevent possible leaks. 12/16 mm
