A spigot is a device used to control the flow of liquid from a container, such as a barrel or drum. It typically consists of a pipe with a shut-off valve at one end and a tapering nozzle at the other. The spout can be opened or closed by turning the valve, allowing for precise control over the amount and rate of liquid dispensed. Spigots are commonly used in various industries to transfer liquids, such as oil or chemicals, from large containers into smaller ones, or to fill equipment directly from a bulk supply.
