Product Function
NHRC pneumatic fittings are designed to connect pneumatic tubing while allowing free rotation without changing airflow direction.
They are ideal for dynamic systems where flexibility, durability, and reduced mechanical stress are critical.
Compared with:
- PC (Straight Fitting) → fixed, no rotation
- NHRC (Rotary Straight) → rotation without direction change
- NHRL (Rotary Elbow) → rotation + 90° direction change
NHRC is the best solution for straight-line installations requiring rotational flexibility.
