rotary joints

Rotary Joint

swivel union is a fluid dynamic sealing device that transports fluid medium from a fixed pipeline to a pipeline or equipment that rotates or swings at a certain angle. Its core function is to establish a reliable connection between the stationary supply channel and the dynamically rotating components, achieving 360° continuous and leak-free transmission of various media such as gas, liquid, and oil
