TUFFJUGS SPOUT AUTO-STOP 1" NPT 5G/20L TUFFJUGS AS20

Unique to Tuff Jug, this spout is internally vented to provide both fast flow and auto shutoff, all-in-one! The internal venting system removes the need for external jug vents that can break or allow fluids to spill out the side of your container. The Auto Stop Spout will only work with a Tuff Jug.
