## Product Summary

NHRC pneumatic fittings are rotary straight push-to-connect connectors designed to provide 360-degree swivel rotation in pneumatic systems.

With a straight-through structure combined with a rotating joint, NHRC fittings allow pneumatic tubing to rotate freely without changing airflow direction, effectively reducing tube twisting, stress, and wear.

This design is ideal for dynamic systems where tubing must move, rotate, or operate continuously.

The push-to-connect system enables fast installation without tools while ensuring secure grip and stable sealing performance.

Nickel-plated brass construction ensures durability, corrosion resistance, and long service life in industrial environments.

OEM and ODM customization services are available for tube sizes, thread types, and branding requirements.

- Straight airflow without direction change

- Reduces tube twisting and mechanical stress

- Ideal for moving and dynamic systems

- Push-to-connect quick installation

- Durable structure for industrial use

### Applications

Automation equipmentUsed in moving parts requiring flexible air connections

Robotic systemsPrevents tubing from twisting during continuous motion

Pneumatic control systemsMaintains stable airflow with rotation capability

Rotating machinerySupports free movement without airflow restriction

Industrial equipmentImproves lifespan in high-motion environments

### 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.
