1/2″ Siphon Stopper® Complete Fitting w/ Bulkhead and Elbow

Siphon Stopper® complete return fitting comes with Siphon Stopper® cap, elbows, loc-line hose with 1/4″ nozzle, 1/2″ Better Bulkhead® , and 1/2″ barbed elbow. This is the best solution to give your aquarium a consistent output position that is easy to manipulate water flow, and at the same time limits your risk of a back siphon much more effectively than a check valve. Please note that a minimum hole size of 1.26″ (32mm) is required for the bulkhead.
