Multi Passage Rotary Union is designed to simultaneously transfer multiple fluids, gases, or hydraulic media between stationary supply lines and rotating equipment. These advanced rotary joints allow several independent flow channels to operate through a single rotating interface, making them essential for automated manufacturing systems, CNC machinery, robotics, packaging lines, and hydraulic systems.
As an experienced rotary union manufacturer in China, we engineer and supply high-precision Multi Passage Unions for global industrial markets. We provide cost-effective alternatives to international rotary union brands such as Deublin, Kadant, and Mosmatic, matching their performance while offering flexible customization and faster delivery.
We manufacture our multi-channel rotary unions using high-grade stainless steel and alloy materials to ensure durability, sealing stability, and a long service life in demanding operating conditions.
A Multi Passage Rotary Union (also known as multi channel rotary joint, multi port rotary union, or multi circuit rotary coupling) is a specialized rotating connector that enables multiple independent media channels to pass through a rotating interface simultaneously.
Unlike a single passage rotary union, which transfers only one fluid path, a multi passage union can integrate several flow paths within a compact housing.
Typical media include:
Hydraulic oil
Compressed air
Water or coolant
Vacuum
Lubricating fluids
Inert gases
Each passage is sealed independently, ensuring no cross-contamination between channels and stable operation even under high pressure or high rotational speed.
Every industrial system has unique requirements. As a professional rotary union manufacturer, we provide full customization services.
Available customization options include:
Number of passages (2–20 channels)
Thread standards (NPT, BSP, Metric)
Flange mounting designs
Special sealing materials
High temperature configurations
High-pressure configurations
We support OEM and ODM manufacturing, allowing customers to develop rotary unions tailored to their equipment specifications.
Our Multi-Passage product category includes various models designed for different industrial applications.
Common configurations include:
2 Passage Rotary Union
4 Passage Rotary Union
6 Passage Rotary Union
