SharkBite 17198-0000 Vacuum Breaker, 3/4 in Female x Male, Brass

The V-3 Vacuum Breaker prevents dangerous back-siphonage and backflow into a potable water supply. The V-3 is equipped with a protruding tip device for manual draining of a faucet (after hose removal), which prevents freezing. The V-3 is also available in a chrome-plated version (V-3C). These units are not intended for use where water contamination could occur as a result of draining or for permanent continuous pressure installation. For continuous pressure systems, install the BFP Dual Check Valve.
