Rotary Unions and Rotary Joints
Rotary unions and rotary joints, also known as swivels or couplings, are precision mechanical components used to transfer fluids—such as water, air, oil, or steam—from a stationary source into rotating machinery. These devices are essential in many industrial applications, including cooling, heating, and fluid power transmission. They are widely used in manufacturing processes to ensure smooth and efficient operation of rotating equipment.
