Barbed fittings are specialized connectors used in plumbing and irrigation systems. They feature a series of ridges or barbs along their length, which help secure hoses or tubing when attached. This design prevents leaks and ensures a tight fit, making them ideal for transferring liquids or gases. These fittings are commonly made from materials like plastic or metal, depending on the application. Barbed fittings come in various sizes and shapes, allowing for compatibility with different hose diameters and configurations. They are widely used in gardening, aquariums, and automotive applications, among others.
