2-Way Pneumatic Rotary Joint – 360° Dual-Channel Central Rotating Union
The 2-Way Pneumatic Rotary Joint (Model GY2T) is a high-performance dual-channel rotating union engineered for continuous 360° rotation in pneumatic and hydraulic systems. With multiple G-thread size options and a robust pressure rating of up to 40MPa, this central rotary joint keeps two independent fluid or air channels active simultaneously — even during full rotation — making it ideal for industrial automation, robotic arms, rotary tables, and precision machinery.
Key Features
- 360° Continuous Rotation: Allows unrestricted full rotation while maintaining dual-channel fluid or air flow without tangling or interruption.
- Dual Independent Channels: Two completely separate internal passages ensure no cross-contamination between circuits.
-
Multiple Thread Size Options: Choose from 6 configurations to match your system:
- A: G1/8A (1 point)
- B: G1/4A (2 points)
- C: G1/4A Compact (2 points)
- D: G3/8A (3 points)
- E: G1/2A (4 points)
- F: G3/4A (6 points)
- High Pressure Rated: Withstands up to ≤40MPa, suitable for demanding hydraulic and pneumatic applications.
- Temperature Resistant: Operates reliably up to 90°C for use in high-temperature industrial environments.
- Max Rotational Speed: Up to 100 RPM for fast-moving machinery and automated systems.
- No High-Concern Chemicals: Constructed without hazardous substances for safe, compliant operation.

Frequently Asked Questions
Q: What does a 2-way pneumatic rotary joint do?
A: A 2-way pneumatic rotary joint (also called a dual-channel rotating union) allows two independent fluid or air channels to pass through a rotating interface simultaneously. This means connected machinery can rotate a full 360° continuously without hoses twisting, kinking, or disconnecting — critical for rotary tables, robotic arms, and automated equipment.
Q: What thread sizes are available for the GY2T rotary joint?
A: The GY2T is available in six configurations: G1/8A (1 point), G1/4A standard (2 points), G1/4A compact (2 points), G3/8A (3 points), G1/2A (4 points), and G3/4A (6 points). Select the size that matches your system's BSP thread specification for a leak-free connection.
Q: What is the maximum pressure and temperature this rotary joint can handle?
A: This rotary joint is rated for pressures up to ≤40MPa and can operate at temperatures up to 90°C, making it suitable for high-demand pneumatic and hydraulic industrial applications.
Q: Is this rotary joint suitable for hydraulic oil or only compressed air?
A: The GY2T dual-channel rotary joint is compatible with both pneumatic (compressed air) and hydraulic fluid systems, provided operating pressure and temperature remain within the specified ratings (≤40MPa, ≤90°C).
