The series of 2-passage rotary joint is a dual flow rotary union slip ring. It is 2 inlet 2 outlet, can rotate 360° and transfer fluid medium in two passages. It has the advantages of small size, light weight, small torque, and multiple gas passages without interference. In addition to standard models, other combinations of passages and transmission current can be customized.

Tips: How to install the rotary joint?
- Place the rotary joint on the device, and then connect the fixing hole of the rotor and the fixing hole of the stator to the corresponding mounting holes of the device.
- Fix the rotor part of the rotary joint. Use set screws to fix the rotary joint rotor to the rotary side of the device.
- Fix the stator part of the rotary joint. Use set screws to fix the rotary joint stator to the stationary side of the device.

2-passage rotary union, pneumatic/electrical slip ring can 360° rotate transfer fluid mediums including compressed air, vacuum, water, steam, oil, hydraulic and other gas/fluid. For power/current/signal transmission, circuits can select 6/12/24/36/56 wires 2A or 12/24 wires 5A. G1/8" port for 6~8mm pipes. Combination of circuit wires and current can be customized.
