Water rotary union

for oilfor compressed air2-passage

Short Description
2-passage rotary union with a 60 mm through bore and stainless steel main body. Designed for continuous 360° transmission of compressed air and liquid media with low-friction composite seals for minimal leakage and stable performance. Suitable for automation, winding and rotary processing systems. Custom configurations available.

Key Features

• Large 60 mm through-bore to permit shaft, cable or piping passage
• Two independent passages to transmit gas and liquid media without cross-contamination
• Stainless steel housing for corrosion resistance in humid or workshop environments
• High-performance composite seals providing low starting torque and minimal leakage
• Supports unlimited 360° continuous rotation to prevent hose twisting
• Modular construction for easy maintenance and seal replacement
• Compatible with compressed air, cooling water, hydraulic oil and low-viscosity fluids
• Customizable ports, threads, rotational speed and pressure rating to meet application requirements
