Tuff Jug Auto-Stop 1" NPT Flexible Spout

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. See our dedicated Auto Stop Spout page here for more information. The Auto Stop Spout will only work with a Tuff Jug.
