A rotary joint, also known as a pressure rotary joint or rotating union abroad, is used to connect external pipelines of mechanical equipment. In the early days, people wrapped sealing materials around rotating shafts to prevent medium leakage by friction and compression. Though low in cost, the technology was primitive. Such solutions only lasted for a few days and required frequent maintenance. Frequent leakage often led to equipment downtime and severely hampered operational efficiency.

Since the 21st century, rotary joints with sealing components made of metal, graphite, rubber and other materials have been widely adopted at home and abroad. They effectively stop leakage and extend service life, helping enterprises boost economic benefits. Most foreign products adopt multi-layer sealing structures for zero leakage, yet their complicated craftsmanship results in difficult and costly maintenance for manufacturers.

In recent years, China has extensively introduced advanced overseas technologies. Domestic manufacturers are now capable of producing full-range rotary joints featuring high cost performance and easy maintenance.
