This connector allows you to hook your Keurig commercial brewers (B150P, B155P, K150P, K155P, K2500) to a water source. You must have the direct water line plumb kit reservoir (water tank). This connector attaches to the plumb kit and the other end has a quick connect fitting to connect to a 1/4" water line. The elbow helps keep the water line out of view for a nice clean looking installation. Helps direct the water line directly to an attachable filter. (sold separately).
