This ¼" Angle Pigtail Siphon has a brass finish. It is used as a hammer arrest for either water or air. It helps to protect gauges and traps from a sudden influx of water or air traveling in the pipe. Inside the siphon is a pocket of air that helps slow down the sudden influx, and thus protects the gauge or trap.
