A hose nozzle is a device attached to the end of a garden hose that controls the flow and direction of water. It allows users to adjust the spray pattern, from a fine mist to a strong jet, making it versatile for various tasks like watering plants, washing cars, or cleaning outdoor surfaces. Most hose nozzles are made of durable materials like plastic or metal and feature a trigger or dial for easy operation. Some models also include ergonomic designs for comfort during use. Properly using a hose nozzle can help conserve water while effectively completing outdoor chores.
