Key Features
- 90° elbow + 360° swivel rotation
- Reduces tube twisting and mechanical stress
- Suitable for dynamic and moving systems
- Push-to-connect quick installation
- Nickel-plated brass body for durability
- Stable and leak-resistant sealing
Applications
Automation equipment
Used in moving parts requiring flexible airflow routing
Robotic systems
Prevents tube twisting during continuous motion
Pneumatic control systems
Ensures stable airflow with dynamic movement
Rotating machinery
Supports rotation and airflow direction change
Industrial equipment
Improves durability in high-motion environments
Product Function
NHRL pneumatic fittings are designed to connect pneumatic tubing while allowing both airflow direction change and free rotation.
This dual function significantly improves system flexibility and reduces wear compared to standard elbow fittings.
Compared with:
- PL (Standard Elbow) → fixed direction only
- NHRL (Rotary Elbow) → direction + rotation
- NHRC (High-speed rotary) → enhanced rotation performance
NHRL is ideal for applications where tubing must move, rotate, or operate under continuous motion.
