rotary joints
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

20+ years of rotary joint engineering experience — offering customized design, sizing guidance, material selection, and on-site technical support for your specific application.
SDSWIVELES integrates 20 years of engineering experience with German-inspired quality management systems to form a standardized production process for precision rotary joints.
Every rotary joint undergoes a documented manufacturing sequence: precision CNC machining, seal face lapping, assembly, and final inspection. Each unit is traceable with individual quality records and serialized documentation.
Our quality department operates with full independence and authority to halt production if standards are not met. Dimensional tolerances are verified to ±0.01mm, and all units are pressure-tested to 1.5x working pressure before shipment.
Triple validation: "dimensional reports + material certifications + performance test records." Product qualification rates remain stable above 99%, eliminating performance variations and ensuring long-term operational reliability.
