Swivel joints are mechanical components that allow rotation between connected parts, preventing hose twisting and reducing wear. Commonly used in fuel, oil, and hydraulic systems, they enable smooth fluid flow while accommodating movement. Swivel joints improve hose lifespan, ease handling, and enhance safety in high-pressure or high-motion applications. Made from durable materials like stainless steel or brass, they are essential for efficient, flexible connections in industrial, agricultural, and fuel transfer operations.
