Garden hose fittings are connectors that allow hoses to attach to spigots, spray guns, sprinklers, and other attachments. They come in various sizes and types, such as couplings, connectors, and adapters, ensuring compatibility with different hose diameters and equipment. Made from durable materials like brass or plastic, these fittings are designed for easy installation and secure, leak-free connections. Proper fittings enhance water flow and pressure, making watering tasks more efficient. Fittings add versatility, enabling users to customize their watering systems to suit specific gardening needs.
