Key Features
- 90° elbow + rotary swivel combined design
- Nickel-plated brass for corrosion resistance
- Allows continuous rotation during operation
- Reduces tube twisting and mechanical stress
- Push-to-connect quick installation
Applications
- Pneumatic automation systems
- Robotic arms and moving equipment
- Industrial machinery
- Rotating pneumatic devices
- Flexible air piping systems
Widely used in pneumatic systems requiring direction change, anti-twist performance, and durable metal fittings for dynamic environments.
Product Function
NHRL fittings are designed to change airflow direction by 90° while allowing tubing to rotate freely, preventing hose twisting and extending system service life.
Compared to straight rotary fittings (NHRC), NHRL provides both rotation and directional control, making it ideal for compact and dynamic piping layouts.
