A spray nozzle is a device that controls the direction and characteristics of a fluid spray. It is commonly used in various applications, including gardening, painting, and industrial processes. The nozzle can create different spray patterns, such as mist, cone, or stream, depending on its design and purpose. Spray nozzles are often made from materials like plastic or metal and can be adjustable or fixed. They are essential in equipment like spray guns, irrigation systems, and pressure washers, helping to optimize fluid distribution and improve efficiency in tasks ranging from watering plants to applying coatings.
