## Product Summary

POC-C pneumatic fittings are mini round male straight push-to-connect connectors designed for compact tube-to-thread connections in pneumatic systems.

With a compact round structure and straight male threaded design, POC-C fittings are ideal for installations where space is extremely limited, such as small valves, mini cylinders, and precision pneumatic equipment.

The fitting features a nickel-plated brass body combined with an O-ring sealing system, ensuring corrosion resistance, secure connection, and long-term reliability.

Push-to-connect technology allows fast installation and easy tube removal without tools, improving assembly efficiency in compact systems.

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