A bib cock, also known as a bib tap or a hose bib, is a type of water valve commonly used for outdoor water supply connections. It is a simple and durable device designed to control the flow of water in a plumbing system. The term "bib" refers to the fact that the tap typically has a short pipe with a threaded outlet, allowing it to be connected to a garden hose or other similar devices. Bib cocks are commonly found in gardens, lawns, and outdoor areas where a convenient water supply is needed for tasks like watering plants, washing cars, or filling buckets. They are designed for outdoor use and are generally not suitable for indoor plumbing applications.
