## Product Summary

PCF pneumatic fittings are female thread straight push-to-connect connectors designed for tube-to-thread connection in pneumatic systems.

With a straight-through structure and internal threaded port, PCF fittings allow direct connection of pneumatic tubing to male-threaded components such as valves, cylinders, and manifolds.

The compact design ensures efficient tube routing without changing airflow direction, making it ideal for linear pneumatic installations and space-saving system layouts.

Push-to-connect technology enables fast tube installation without tools, ensuring secure connection and reliable sealing performance.

Nickel-plated brass construction provides corrosion resistance, mechanical strength, and long service life in industrial environments, while internal sealing ensures leak-free operation.

OEM and ODM customization services are available for thread type, tube size, and branding requirements.
