Universal Swivel Joint

Our universal swivel joint (also known as rotary union) is a high-performance fluid connection component designed for rotating and swinging pipeline systems. It enables 360° unlimited rotation between fixed and rotating pipelines, effectively preventing pipeline winding, twisting and fatigue damage, ensuring continuous and stable transmission of hydraulic oil, water, steam, gas and other fluids. Manufactured with premium materials and precision sealing technology, this flange-type swivel joint delivers exceptional pressure resistance, zero leakage performance and long service life. We provide fully customized solutions, including various sizes, pressure ratings, flange standards, materials and structures, to meet the unique connection needs of different industrial equipment and working conditions. Widely used in construction machinery, metallurgical equipment, paper machinery, ships, hydraulic stations and other industries, it is an essential component for solving pipeline connection problems in rotating scenarios.
